Kanye West shares four children with his ex-wife, Kim Kardashian.

Kanye West sees Bianca Censori as the perfect stepmom to his and Kim Kardashian’s four children. The 46-year-old rapper took to Instagram on Saturday to share a birthday tribute to the woman he refers to as his wife.

West and Censori had a private wedding ceremony in January 2023, but it has been widely reported that the marriage is not legally binding.

Posting a close-up headshot of Censori to his Instagram, West wrote, “Happy birthday to the most beautiful super bad iconic muse inspirational talented artist masters degree in architecture 140 IQ loving by my side everyday when half the world turned their backs on me and the most amazing step mom to our children I love you so much thank you for sharing your life with me.”

West has wiped his Instagram page clean, posting a series of racy images of Censori to his controversial account.

West and his ex-wife, Kim Kardashian, share four children — North West, 10, Saint West, 8, Chicago West, 5, and Psalm West, 4.

Kardashian has not publicly commented on her ex’s marriage to Censori. On this past season of The Kardashians, Kim shared that North preferred going to Kanye’s house.

“She’ll be like, ‘Dad is the best. He has it all figured out. He doesn’t have a nanny. He doesn’t have a chef. He doesn’t have security. He lives in an apartment.’ And she’ll start crying, ‘Why don’t you have an apartment? I can’t believe we don’t have an apartment.'”

Kim also shared that she’d hired a “manny” (male nanny) to have a male presence in her children’s lives amidst her female-dominated family.

Saying Kanye “has been so nice to him,” Kim shared Kanye’s advice to the “manny.”

“[The ‘manny’] handed [Saint] the ball really easily, or something, and he’s like, ‘Don’t do that, make him go get it himself. These are some of the rules that I would want,'” Kim shared, adding, “And I was like, ‘Oh my god, OK. That’s great!'”

Kim filed for divorce from Kanye in February 2021. The exes have had a tumultuous split through the years. But Kim maintains that their kids aren’t aware of Kanye’s more controversial scandals, like his anti-Semitic comments, which he recently apologized for.
