Nope, that's not Cher you're seeing — it's Kim Kardashian!
The Keeping Up star attended the Casamigos Halloween party on Friday in Los Angeles wearing a stunning Cher costume — and the Believe singer even approved of the look on Twitter.
"You Look BEAUTIFUL Little Armenian Sister," Cher tweeted to Kardashian, adding a kiss emoji.
Kardashian responded to the pop icon, tweeting, "I love you so much!!!"
She was joined by TV personality Jonathan Cheban at the event, who dressed up as Cher's former husband Sonny Bono.
The pair posted videos to social media lip-syncing to some of Sonny & Cher's hits including the 1965 hit I Got You Babe.
Then on Saturday, Kardashian continued her Halloween theme of "music icons," and dressed gave fans a glimpse at two other costumes.
First, she shared a video of herself dressed as Aaliyah.
Then, she shared clips of herself as Madonna with sister Kourtney Kardashian dressed like Michael Jackson.
Kim AKA Cher AKA Madonna posted the photos that inspired the costume with Kourtney.
