If you’re binging Nobody Wants This and thinking, “Who’s this fantastic up-and-coming show creator, Erin Foster?”, you’re in desperate need of a pop culture lesson, my friend. Erin is Hollywood. She’s known for her podcast, The World’s First Podcast, with her 90210 alum sister, Sara Foster, and they’re the daughters of music icon David Foster. But that’s not even close to all of Erin’s famous connections. She comes from a wild Hollywood web, woven by David, who’s been married, well, more times than Donald Trump. Over the years, the Foster sisters have had several famous stepmoms and famous step-siblings as well. This family lore is really something else. Walk with me as I break down Erin Foster’s famous family tree, which includes Gigi and Bella Hadid, Brody and Brandon Jenner, and more celebs.

A Breakdown Of Erin Foster’s Famous Family

All Of Erin Foster’s Famous Family Members

Some people find their one true love, and some people find five wives — David Foster is in the latter category. David himself is a renowned producer, songwriter, and music exec with 16 Grammys. That’s a man who got his ass up and worked in between all the weddings! Naturally, all of his wives have also been famous people in the entertainment industry. David’s first wife, B.J. Cook, is also a musician, and his second wife (and Erin and Sara’s mother), Rebecca Dyer, is a former model.

Although I’m sure he hoped the third time was the charm, we all know it was not. David was married to his third wife, songwriter Linda Thompson, from 1991 to 2005. Linda, of course, shares two sons, Brandon and Brody Jenner, with former Olympian x reality star x MAGA lunatic, Caitlyn Jenner. Little did Erin and Sara know, Brandon and Brody Jenner were not gonna be their only famous step siblings. Nope. After Linda, David married Real Housewives of Beverly Hills star and extremely intense mother Yolanda Hadid. As I sincerely hope you know, Yolanda is the mother of Gigi and Bella Hadid, two of the most important pop culture figures of the last decade. David split from Yolanda in 2017, and he married American Idol star Katherine McPhee in 2019. They’re still married now, but will it last? Well, the stats say no, but we’ll see.

Erin is actually quite close with Katherine, who is a few years younger than her. “The truth is having a stepmom who’s the same age as you is so much better,” Erin told Andy Cohen on Watch What Happens Live. I aspire to this level of… optimism. “It’s so fun. We’re the same age, we like the same things. And so, it’s more like having a sister. We, just, are like friends. It’s nice.” An impressive glass half full spin if I’ve ever seen one.

Where Does Erin Foster Stand With Gigi Hadid, Bella Hadid, Brody Jenner, And Brandon Jenner?

Apparently, Erin and the Hadid sisters are still tight. During her recent appearance on Watch What Happens Live, the Nobody Wants This show creator confirmed that she still keeps in touch with Gigi and Bella. “Gigi actually just DMed me last night saying she was starting to watch the show,” Erin revealed to Andy. She added, “The kids don’t get divorced, just the parents do.”

David marrying several women and raising other children wasn’t easy for Erin and Sara, and the Foster sisters have some particularly complicated feelings about their Jenner step-siblings. In a 2019 episode of their Sibling Revelry podcast, they opened up about David raising Brody and Brandon Jenner. “He wasn’t raising us,” Sara said. “He was raising Brandon and Brody. I was dealing with my whole own emotional turmoil, which was watching my father raise other children. That was the thing that kept me up at night.”

Erin recalled, “We never lived with our dad after our parents broke up.” She pointed out that David was off living in a $20 million house with Brandon and Brody. “Mine was less resentment toward them,” she said about the Jenner boys. “It was more like, we’re misunderstood out in the world, because we have this fake, spoiled lifestyle, but we’re not even really allowed to be a part of it.” Oh, to be a misunderstood nepo baby. David, you are one messy man.
