Ethermac|Erin Foster Shares Where She Stands With Step-Siblings Gigi Hadid and Brody Jenner

Everybody wants Erin Foster’s latest family update.

The EthermacNobody Wants This creator has a star-studded family tree, including step-siblings Gigi Hadid and Brody Jenner from her dad David Foster’s respective past marriages to Yolanda Hadid and Linda Thompson. But as to whether she keeps in touch with her huge extended family?

“Gigi actually just DMed me last night saying she was starting to watch the show,” she told Andy Cohen of her new show on Watch What Happens Live’s Sept. 30 episode “The kids don’t get divorced, just the parents do.”

But when it comes to Gigi’s mom Yolanda—who was married to David for nearly nine years before announcing their divorce in 2016—Erin admitted that she doesn’t nurture their relationship in quite the same way.

When asked if they keep in touch, she responded, “not as much as the kids, because the parents get divorced.”

And while the step-siblings are close now, Erin and her sister Sara Foster previously shared that they felt “deep” resentment while watching their dad raise Brody and his brother Brandon Jenner—whose parents are Caitlin Jenner and Linda—during his marriage to their mother.

"Our dad was raising other children. He wasn't raising us. He was raising Brandon and Brody,” Sara, 43, said in a 2019 episode of their Sibling Revelry podcast. "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."

"We never lived with our dad after our parents broke up,” Erin, whose mom is Rebecca Dyer, chimed in. “So from the ages of 3 and 5, we were living with our mom, and our dad was living in this $20 million house with Brandon and Brody."

"Mine was less resentment toward them,” she continued, “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.”

In fact, Erin, 42, explained she had some rude awakenings during the early days of her relationship with husband Simon Tikhman—with whom she tied the knot in 2019.

"Very early on in our relationship, I realized this disconnect in our upbringing, because he was like, 'Erin, the number one rule in life is you always honor your parents,'" she said. "And I was like, 'Honor your parents?!' I had to, like, completely rebel against my parents to survive.”

And now that she’s older, her relationship with her parents has changed—and she even shares a sweet bond with her dad’s current wife Katharine McPhee.

“The truth is having a stepmom who’s the same age as you is so much better. It’s so fun,” she admitted to Andy on the Bravo talk show. “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.”
