On Friday night, Kim and her friend Jonathan Cheban pulled off a spot-on pair costume of Sonny Bono and Cher, which even earned her a compliment from the "Believe" singer herself. Mrs. West also dressed up as Madonna and Michael Jackson at the 1991 Oscars with her sister Kourtney and paid tribute to the late R&B singer Aaliyah as well.
