Stars who can't stand Christina Aguilera

We're just going to say it: Christina Aguilera broke the mold of the traditional Y2K pop star. The belly-baring, soulful crooner hit the scene hard in the late 1990s and early 2000s, ditching the bubblegum pop sounds of that era for raw tunes about sex, love, and self-confidence. She was a feminist before it was a popular stance for pop stars, releasing power anthems like 2002's "Can't Hold Us Down," and an advocate for LGBTQ rights well before it was really a thing in the entertainment world.

It's all paid off in her favor, too. Aguilera has had multiple top 10-charting albums on the Billboard 200, millions of her albums sold, a handful of Grammy Awards, and a legion of fans adoring her each and every move. But not everyone has liked her over the years. In fact, there are many people who downright can't stand her. Keep reading for all the stars who have had something to say about Christina Aguilera.

The Wanted want nothing to do with her

As relatable as Aguilera may seem, The Wanted said she's a real diva act behind the scenes. Speaking to New York's 92.3 FM radio station in 2012, the boy band claimed that Aguilera gave them a serious cold shoulder after they performed on the NBC competition The Voice. "She was a bit scary to be honest," band member Max George said (via The Hollywood Reporter). 

"She was a total b***h!" Tom Parker blurted out in agreement, adding, "She might not be a b***h in real life, but to us, she was a b***h to us. She just sat there and didn't speak to us." Siva Kaneswaran echoed their comments, saying that Aguilera was "quite rude."

Two days later, after a source close to the situation denied that anything could have happened between Aguilera and the band, Parker apologized for the remarks — kind of. He told TMZ, "We shouldn't have said it, to be honest with you. We just think manners cost nothing, you know what I mean?"

Mariah Carey has some choice words

The battle between Christina Aguilera and Mariah Carey started in 2006, when Aguilera told GQ that the "Heartbreaker" singer had once said "really derogatory" things to her at a party, and she insensitively brought up Carey's 2001 mental breakdown. "One time, we were at a party and I think she got really drunk, and she had just really derogatory things to say to me," Aguilera explained. "But it was at that time that she had that breakdown, so she might have been very medicated" (via People).

Of course, the shade queen hit back at her twice as hard in an interview with Access Hollywood, accusing Aguilera of displaying "questionable behavior" and using her name for promotional gain. "I had hoped that Christina was in a better place now than the last time I saw her, when she showed up uninvited at one of my parties and displayed questionable behavior," Carey mused (via PopSugar). "It is in my heart to forgive and I will keep her in my prayers."

It wasn't enough to stop Aguilera, though. In 2015, an insider told The National Enquirer that Aguilera downright roasted both Carey and Britney Spears for having Las Vegas residencies. She reportedly said (via Celeb Dirty Laundry), "I won a Grammy this year! Why would I go to Vegas and join Britney and Mariah in an oldies act?"

Carey never responded to the barb, seemingly taking her classic "I don't know her" approach to their beef.

Miley Cyrus was shocked by Xtina's behavior

You're not going to believe this one. Miley Cyrus was once allegedly mad at Aguilera for complimenting her chaps — and yes, you read that correctly.

In 2014, Radar Online reported that Cyrus refused to appear on The Voice after Aguilera tweeted a message about her wearing the garment at a concert. Many people thought Xtina was simply praising Cyrus' look, as she tweeted, "Cheers from one dirrty girl to the next @MileyCyrus…wear [those chaps] loud & proud, girl-yes!" However, Cyrus reportedly believed the singer was shading her for mimicking Aguilera's "Dirrty"-era fashion sense. "Miley couldn't believe Xtina would tweet about her wearing chaps on stage, reminding everyone that she did it first," a source shared with Radar. "It was such a fake compliment and undermined Miley in the process."

By 2016, however, Cyrus had joined The Voice as a key adviser, where she and Aguilera reportedly bonded, often dancing and playing around together, per the Daily Mail. But it proved to be short-lived. After Cyrus took Aguilera's spot on the show, a source told Radar that Aguilera was "[holding] a grudge" over the "Wrecking Ball" singer replacing her. It looks like she hasn't gotten over it yet, as of the time of this writing, either, because in May 2018, she appeared to give Cyrus a taste of her own medicine by copying her look from Cyrus' 2015 music video for "Dooo It!"

Eminem delivered some harsh lyrics

Eminem has seen his fair share of beefs over the years, and he once had a feud with the pop princess herself.

Per Billboard, it all started in 2000, when Aguilera gave an interview to MTV News criticizing Em's violent lyrics towards his on-off girlfriend Kimberly Scott, whom he was actually secretly married to at the time… which Aguilera also leaked in the interview.

After finding out she blew the lid off his secret nuptials, he issued a serious diss to her in his 2000 song "The Real Slim Shady." In the track, he accuses Aguilera of giving him an STD and, um, performing certain acts on MTV VJ Carson Daly and Limp Bizkit's Fred Durst.

The "Fighter" in Aguilera ultimately swept in for the win with a parody rap called "Will the Real Slim Shady Please Shut Up," in which she rapped (per People): "Little twit blasts me on his new CD. Why? / 'Cause I turned him down for a date / As for the question of who came first / Was it Carson Daly or was it Fred Durst?/ I'm sorry Slim, but this is gonna hurt / They both came closer than you ever will, jerk." Oof.

The two would later appear to bury the hatchet with a hug backstage at the 2002 MTV VMAs. But you be the judge of whether that was genuine or just Em trying to save face for Aguilera — y'know, after she beat him at his own game and all.

Pink stood her ground

Pink and Aguilera's relationship reportedly reached a crossroads in the early 2000s when they — along with Mya and Lil' Kim — were collaborating on "Lady Marmalade" for the 2001 Moulin Rouge! soundtrack. According to Pink, there was a dispute over who would sing the high notes on the track, subsequently leading to a series of public and private spats between them. Things got so heated that Aguilera even allegedly tried to fight Pink in a club once. "I was like, 'What's happening right now? What are you — what's happening?'" Pink recounted on an episode of Watch What Happens Live.

Years later in August 2017, however, Pink let it be known on Twitter that she and Aguilera were no longer at odds. She also reiterated the comments on Watch What Happens Live, telling host Andy Cohen, "She's a really sweet person. … We made up on The Voice because I hadn't seen her in years and years and years and we became moms. We grew up, and we hugged it out. It's that simple, and I feel so good about that." That said, we guess the famous "scowl" she gave her former rival while Aguilera covered Whitney Houston's "I Will Always Love You" at the American Music Awards later that year was just coincidence.

Britney Spears couldn't believe her pop star rival

Aguilera pulled no punches about her feelings for Britney Spears in a December 2003 interview with Blender, which started a years-long feud between them. She told the magazine (via E! News) that the "Toxic" singer was "distant" during rehearsals for their 2003 MTV Video Music Awards performance with Madonna and that she "seems like a lost little girl, someone who [desperately] needs guidance."

Spears didn't take it kindly, telling Blender the following month (via Us Weekly), "A lost girl? I think it's probably the other way around. I can't believe she said that about me." She also offered up an explanation for her "distant" behavior, saying, "When someone has been rude to you so many times, it's like, 'You know what, Christina, I'm really not about the fake anymore.'"

From there, Aguilera got even ruder. Speaking to Us Weekly in 2004, the "Beautiful" singer ripped Spears for proposing to her now-ex Kevin Federline and buying her own engagement ring. "It looks like she got it on QVC," she said of the five-carat sparkler. When asked about her thoughts on their wedding, Aguilera quipped, "I know Britney. … She's not trailer trash, but she sure acts that way." Buuurn.

While Aguilera has since tried to make amends, don't count on seeing these two braiding each other's hair extensions any time soon.

Aaron Lewis didn't hesitate to judge

The national anthem is one of those songs that — no matter how difficult the lyrics might be — you better always get right. But Aguilera didn't when she performed her rendition of the song at the 2011 Super Bowl. She sang, "What so proudly we watched at the twilight's last reaming" instead of "O'er the ramparts we watched, were so gallantly streaming." And Staind frontman Aaron Lewis slammed her for it, insisting she'd switched up the lyrics on purpose (although she said otherwise). "I guess I don't understand how people who sing the national anthem can be so f**king self-absorbed that they would try to change that f**king song," he ranted. "If there is a single song in the history of this country that deserves no creative interpretation, it's that one."

Considering how offended he was by the gaffe, you'd think he'd know all the lyrics to the song himself. But when he was given the honor in 2014 at Game 5 of the World Series, he arguably butchered the anthem even worse than she did. The word "karma" comes to mind…

Kelly Osbourne got nasty

If there was any chance that Kelly Osbourne would become a fan of Christina Aguilera's, the pop star's 2000 Christmas album My Kind Of Christmas ruined it. Osbourne slammed the album in an episode of The Osbournes, and, after mocking Aguilera's vocals, she declared, "I'm not kidding you — I wanted to f**king stab myself." She later roasted Aguilera in the press, saying, "She is one of the most disgusting human beings in the entire world," and "I've seen drag queens who look better."

Aguilera followed up by confronting her at a club, and, when that failed, she started dishing it back at Osbourne, which got Osbourne even more riled up. As noted by MTV News, she responded to Aguilera's actions in 2003 by calling her music "crap" and calling her a "cow." Things were quiet for a while after that, but, in 2011, Aguilera purchased the Osbourne family home, which led to a fiery, body-shaming clapback from Osbourne in a 2011 episode of Fashion Police. "Maybe she is just becoming the fat b***h she was born to be," she said of Aguilera's weight gain (via Us Weekly). "I don't know. She was a c**t to me. And she bought my house! She called me fat for so many f**king years, so you know what? F**k you! You're fat too."

Osbourne appeared to end the feud on Watch What Happens Live in 2012, but, with all the back and forth, we reckon this isn't the end of it.
