Kim Kardashian's Cher Halloween costume received the ultimate stamp of approval

Kim Kardashian West showed up to George Clooney and Randy Gerber's Casamigos Halloween party on Friday dressed as Cher. And on Saturday, she received the ultimate costume endorsement: approval from Cher herself.

The reality star's ensemble was a recreation of Cher's look from the 1973 Oscars, during which she presented the award for Best Original Song alongside then-husband Sonny Bono.

Kim also had a "Sonny" in tow on Friday: her best friend Jonathan Cheban, who was once absolutely roasted by Martha Stewart.

No roasting from Cher, though. She loved it all. "You Look BEAUTIFUL Little Armenian Sister," she tweeted at Kim on Saturday morning.

Naturally, Kim seemed thrilled by the compliment. After all, she does consider Cher her style icon.
