Courtney Taylor Olsen: Who Is The Olsen Twins' Other Sister?

The Olsen twins are famously private, which is likely why most people tend to forget that there are more Olsen siblings than just Mary-Kate and Ashley. There's Elizabeth Olsen; Trent Olsen; half-brother, Jake; and their half-sister, Courtney Taylor Olsen. While Elizabeth is already making a name for herself in Hollywood, Trent, Jake, and Courtney still seem to be getting their careers off the ground. 

Born in 1996, Courtney is the daughter of Mary-Kate and Ashley's dad Dave and his second wife, McKenzie. According to The Richest, Courtney starred in two movies, "Malignant Spirits: Sense of Fiction" and "YOLO: The Movie," but she hasn't been in anything else since, so it remains unclear whether or not she wants to really get into the entertainment industry.

Still, the outlet estimates that she's likely worth anywhere from $100,000 and $1 million, which is a huge gap, but makes sense when you consider that her parents and half-sisters are loaded. Maybe her wealth is just from family. 

Courtney Taylor Olsen stays out of the spotlight

If she's anything like her half-sister Elizabeth Olsen, it's likely that Courtney Taylor Olsen is trying to distance herself from Mary-Kate and Ashley's career. It can't have been easy growing up with two of the most famous women in the world — generations of people grew up watching the Olsen twins play Michelle Tanner on "Full House" and then go on to a successful movie career before leaving film and TV to launch their fashion empire. 

There aren't a lot of interviews or even information out there on the internet about Courtney Taylor, but it's likely that she has a similar relationship to the Olsen twins as Elizabeth. Despite rumors that the twins have contentious relationships with their siblings, they do at least seem to take interest in their sisters' lives.

For example, Elizabeth said that the twins helped her learn how to be just as coy in interviews as they are. She told Modern Luxury (via People), "They'd say, 'You know, even if you don't think anyone's going to read this article, someone might pull the quote later for [something else].' It's all part of how you hope someone interprets you, and how they frame who you are and the work you do. They're very tight-lipped — notoriously so." Judging by the lack of info out there about Courtney, it looks like she got the same advice. 

Details about Courtney Taylor Olsen are pretty scarce

The Olsen twins' half-sister Courtney Taylor is on Instagram, but other than that, she keeps a very low profile, which seems to run in the family. It's not that they're snobs or anything though, it seems, based on some of Elizabeth's comments about learning how to navigate Hollywood. It's anxiety, really. She told Modern Luxury (via People), "I still deal with so many anxieties of how I come across. I'll go home at night, spinning with a guilt complex of, 'Did I say something stupid to that person who I respect? Do they think I'm a freak?' I don't want to think like that anymore."

Of course, that's Elizabeth talking and not Courtney, who might not even be going into show business, but it's safe to say that the entire family shares a similar outlook about when and why one talks to the press. Until she has a career of her own, or one of the twins actually mentions her name in public, fans of the Olsen family will just have to sit tight for more details on Courtney. 

Courtney Taylor Olsen supports Elizabeth Olsen's career

Courtney Taylor Olsen may not be a famous figure like her sisters, however, she's still willing to support at least one sibling's fame. That might be clear to anyone who has attended a premiere for a movie that featured Elizabeth Olsen in the past few years. Those who follow Courtney on social media may also know that she popped up at the world premiere of "Avengers: Infinity War" back in April 2018, which saw Elizabeth continue her role as Wanda Maximoff, aka Scarlet Witch, per IMDb. Posting a photo of herself on Instagram where she can be seen glancing at a poster that features Elizabeth's face along with other cast members of the Marvel movie, Courtney added a caption that read: "Just admiring my bad*** of a sister."

Courtney seemed to be just as thrilled to be at another event to support Elizabeth in May when she showed up on the red carpet during the world premiere of "Doctor Strange in the Multiverse of Madness." Along with posting a collection of photos to Instagram that featured herself and her guest riding in a car and posing with the film's massive poster, she wrote, "Big Wanda fans over here."

Courtney's Intagram followers seemed to love what they saw with the latter post, with "Cory in the House" actor Madison Pettis adding a heart-eyes emoji. That's right, Madison Pettis, who happens to be Courtney's friend, and TBH, these two longtime pals are absolutely adorable together.

Courtney Taylor Olsen is friends with former child star Madison Pettis

If you watched the Disney Channel back in the day, then you may know Madison Pettis as Sophie Martinez from "Cory in the House," per IMDb. She also played Allie Brooks on "Life with Boys," Janelle on "Lab Rats," and Natasha 'Tosh' Bennett on "Five Points." That's not to mention the fact that she was the voice of Adyson Sweetwater on "Phineas and Ferb" and Izzy on "Jake and the Never Land Pirates." However, Courtney Taylor Olsen knows Pettis as a good friend.

The two have apparently been close for years. For instance, back in July 2014, Olsen posted a birthday message to Pettis on Instagram that showed the pair posing together. In the caption, Olsen wrote, "My darling dear Madison I love you so much you are my go to gal, I'm so blessed to have someone like you in ... my life you are so mature, gorgeous, funny and I don't know what I would do without you...Happy 16th lovey can't wait to celebrate! Love you with all my heart."

In July 2020, Olsen used Instagram to again post about Pettis' birthday, this time noting that various members of their friend group tested negative for coronavirus, meaning they could celebrate together. The duo's relationship still seemed to be going strong in April, when Olsen shared a pic of the pair enjoying chicken and waffles together. Pettis replied using an emoji with its tongue out and simply wrote, "Yum."
