Kim Kardashian and Jonathan Cheban Are Sonny and Cher for Halloween

When Kim Kardashian needed a friend to help her with her Halloween costume, Jonathan Cheban was like, “I got you babe!”

He and the Keeping Up With the Kardashiansstar dressed up as the late Sonny Bono and pop superstar Cher for the 2017 Casamigos Halloween Party. Kim wore a yellow, long sleeve, bohemian-style crop top and flared pants with sparkling embellishments. Jonathan wore a wig and fake mustache and plum checkered tux. She also sported a long, dark brown wig—similar to her own natural hair—over her platinum blond locks.

Kim seemed relaxed and in a great mood. She chatted with model Kelly Sawyer, who was dressed as a cheerleader, as well as other pals. After a few minutes outside, Kim and Cheban linked arms and walked inside the party, did a small lap and left, E! News has learned.

They later had a blast filming Snapchat videos of themselves lip-synching the former couple’s 1965 hit “I Got You Babe” and Cher’s 1998 dance song “Believe.”
