It looks like Caitlyn Jenner‘s relationship with her new girl is causing even more issues in the Kardashian/Jenner family. The retired gold medal-winning Olympic athlete is currently dating 21-year-old transgender model Sophia Hutchins and sources exclusively reveal to Life & Style that Caitlyn’s daughters Kylie Jenner, Kendall Jenner, and Kim Kardashian do not approve of their relationship at all.

“They’ve heard from friends that Caitlyn’s dating Sophia, and it upsets them like you wouldn’t believe,” an insider tells Life & Style. “She’s their age! They feel a mix of jealousy and distrust about it.”

Since August, Caitlyn and Sophia have been inseparable. They’ve been spotted out doing almost everything together, like going on a Chipotle run, jetting off on a Mexican vacation, and even attending Kendall’s 22nd birthday party last month. Kendall is only one year older than her father’s new girlfriend, and Kylie is one year younger — so it’s completely understandable why they feel uncomfortable with the 68-year-old dating someone so close to their age. And even though Caitlyn insists that she and Sophia are only close friends, her daughters aren’t buying it — and they definitely don’t like it!

They’re not the only ones who don’t approve. Their big sister Kim Kardashian, 37, “is very suspicious of Sophia, too,” says the insider. And when they ask Caitlyn what’s really going on with Sophia, “she hems and haws and doesn’t really give them a straight answer,” the insider says. “Sometimes she calls Sophia her ‘protégé.’ There are a lot of mixed signals and questions the girls want answered.”

This is just yet another thing chipping away at the distance between Caitlyn and the Kardashian family, who refuse to speak to Caitlyn because they are unhappy with the way she handled herself, her transition, and her divorce from their mother, Kris Jenner.

“It’s been a little bit tough over the last couple of years on the Kardashian side. To be honest, I don’t talk to them anymore. Kim, I haven’t talked to in a year,” she said during an appearance last month. “They don’t want me in their lives, they bashed me pretty badly. It’s devastating when your kids do that. It really hurt.”
