Sources Say Kanye West “Never Pretended He Was Happy’ About Estranged Wife Kim Kardashian Moving on with Pete Davidson

Kanye West is still dealing with his pending divorce from estranged wife Kim Kardashian, who seems to have moved on.

The 44-year-old rapper has “struggled” watching the mother of his four children date Pete Davidson, a source close to West told PEOPLE.

“It’s very hard for him that Kim has moved on. This is something he has struggled with since Kim started dating Pete. He never pretended he was happy about it,” the insider says. “He doesn’t want Kim to date, Pete. Or anyone else.”

Speaking to Jason Lee during filming for an upcoming episode of Hollywood Unlocked, West asked the host, “How you gonna bring me to SNL and kiss the dude you dating right in front of me and everybody’s like, ‘Aw, that’s cool?'”

The Chicago native is referring to an Aladdin sketch where Kardashian and Davidson kissed when she hosted Saturday Night Live this past October.

The dating rumors began that same month when Kim and Davidson were seen holding hands while riding a roller coaster at Knott’s Scary Farm in Buena Park, California, after appearing on the late-night show.

West felt the 41-year-old reality star would reconsider their divorce regardless of her new fling.

“To Kanye, he and Kim are still married. He always thought Kim was gonna change her mind about the divorce. His whole life is in turmoil,” the source adds. “He is trying his best to stay busy with work and [new girlfriend] Julia [Fox].”

The Grammy winner also has a new romance with Fox, which he made public with a racy photo shoot last week. However, a second insider previously told PEOPLE that he still wants to get back with the Keeping Up With The Kardashians alum.

“He’s still telling people that he wants to have Kim back and he is willing to make appropriate changes to do so,” the second source revealed.

The source adds that West “has no plans at this time to start a long-term relationship.”
