Shady secrets of the Glee cast

If you go by the the tabloids, Fox's musical comedy series Glee was the worst set to work on since Bruce Willis and Cybill Shepherd went at it behind the scenes of Moonlighting. What went wrong? From screaming matches to accusations of child pornography, check out some of the Glee castmembers' shadiest secrets.

Naya Rivera allegedly feuded with Lea Michele...

According to multiple outlets—among them TMZ—co-stars Naya Rivera and Lea Michele got into an all-out screaming match while filming an episode of Glee in April 2014. Sources claimed Rivera lost her cool due to Michele's diva-like behavior on set; Michele's camp denied otherwise. Then came rumors that Rivera had been completely fired from the show, which Rivera's camp, as well as the network, Fox, were subsequently forced to deny, even though Rivera's character had mysteriously been written out of Glee's season five finale. To this day, nobody quite knows what the hell happened, although a report from July 2015 claims that Rivera plans to write about her feud with Michele in her upcoming memoir. Now, if only this kind of juicy drama actually happened on the show.

...And Mark Salling

In 2010, US Weekly reported that Rivera went off on her co-star and casual boyfriend, Mark Salling, after finding out that Salling had been hooking up with other women. According to the report, Rivera "went crazy when she read about other girls" and proceeded to egg and key his Lexus. A subsequent report even claimed that she and her girlfriends put dog food all over his car. While Rivera may have been upset then, she ultimately dodged a bullet. That's because…

Mark Salling got arrested for kiddie porn

At the end of 2015, Salling, 33, was arrested on suspicion of possessing child pornography. TMZ reported that the LAPD's Internet Crimes Against Children Task Force raided Salling's home on December 29 and found hundreds of images on his computer, many featuring children "significantly younger than 15 and 16 year olds." The LAPD was reportedly tipped off by Salling's ex-girlfriend. Salling subsequently posted $20,000 bail. As of this writing, his fate remains uncertain.

He's also been accused of sexual battery

In 2013, TMZ reported that Salling was sued for sexual battery by an ex-girlfriend, Roxanne Gorzela, who claimed that Salling forced her to have sex with him without a condom in 2011. Gorzela also alleged that Salling threw her to the ground, causing her to injure her knees, when she confronted him about possibly contracting an STD. The suit was ultimately settled in 2015. Salling agreed to pay a shocking $2.7 million to Gorzola, $64,155 and $666,000 of which would go to past and future medical bills, respectively, according to TMZ. Ew.

Dianna Agron mysteriously missed the Cory Monteith tribute episode...but why?

Dianna Agron was noticeably absent from the 2013 episode "The Quarterback," which was dedicated entirely to the late Cory Monteith, who died of a drug overdose that year. Agron's absence was especially odd, considering her character, Quinn, became pregnant by Monteith's character in season one. So, what the hell happened? Some sources alleged that creator Ryan Murphy and co-star Lea Michele blocked Agron from appearing in the episode because they didn't like her; Murphy shrugged it off, claiming he thought she was working at the time and that any non-contracted actor who asked to be featured in the episode was ultimately written in. Agron ultimately, but not really, addressed her absence during an interview with The Irish Independent. "I've nothing but love for that show and everybody involved in it," she said. Strange, no?

Lea Michele was once hot for teacher

In her 2014 memoir, Brunette Ambition, Lea Michele admitted she once dated Matthew Morrison, the actor who would go on to play her teacher on Glee. "I had worked on Broadway with Jenna Ushkowitz and Matthew Morrison before," Michele, who was only 23 years old when Glee premiered, wrote. "Matt had been a friend of mine for years, and in fact we'd actually dated back in the day for a Broadway beat." We're not sure how long a "Broadway beat" is; but given the age difference between Michele and Morrison, it's enough to make us shudder, anyway.

And she's still getting publicity about Cory Monteith

After Cory Monteith died of a drug overdose in 2013, Monteith's on-again, off-again girlfriend Lea Michele understandably became a symbol of strength during tragedy; her tearful speech at the 2013 Teen Choice Awards was memorably touching. But in the years since, some have criticized the actress for speaking about Monteith to get publicity. Case in point: a January 2016 interview with the Fempire podcast, during which Michele claimed that Monteith would have loved her new boyfriend, Matthew Paetz. That's all well and fine—but also the last thing that Paetz probably wants to hear right now.

Pretty much nobody attended Heather Morris' baby shower

In 2013, the sleuths over at Wetpaint noticed that many of the female actresses on Glee missed co-star Heather Morris' baby shower. Among those who allegedly missed the party: Lea Michele; Dianna Agron; and Amber Riley. In fact, Wetpaint surmised that Naya Rivera and Vanessa Lengies were the only Gleemales (sorry) who showed up. Why the no-shows? Wetpaint claims that some of them were traveling or busy working or all that jazz; but given the high frequency of feuds on and off set, you can't help but wonder if something else went wrong.

Jane Lynch was once addicted to cold medicine

In her 2011 memoir, Happy Accidents, Emmy-winning actress Jane Lynch wrote honestly about her struggle with alcoholism. During her quest to quit drinking, Lynch writes that she eventually became hooked on NyQuill. "Though no longer drinking Miller Lite I was in need of something to soothe me," she writes. "The fact that NyQuil had alcohol in it was not something I acknowledged at all. I still considered myself on the wagon." She finally quit drinking for good in 1991, and attended Alcoholics Anonymous in 1992. She's been sober ever since.
