Kim Kardashian is Cher!

After teasing fans on social media, the 37-year-old reality star finally debuted her “HallowKKWeen” costume on Friday night.

Kardashian once again channeled Cher while Jonathan Cheban stepped in as Sonny.

“Here’s a hint… #HallowKKWeen,” she captioned a pic of a long black wig Friday evening, before revealing her and Cheban’s “inspo for the night.”

Hours later, Kardashian emerged looking like Cher’s carbon copy, lip syncing to the icon’s songs, including "Believe" and "I Got You Babe," as Cheban goofed off in the background.

Kardashian and Cheban headed to the annual Casamigos Tequila Halloween Party, where the reality star opened up to ET about her costume, saying that Cher is her "idol" and that the get-up was perfect for the '70s themed party. Also on hand at the annual bash were stars like Jon Hamm, Molly Sims and more! 

On Saturday morning, Kardashian got this message from Cher herself on Twitter: “@KimKardashian Woke To See You Are Me 4 🎃You Look BEAUTIFUL Little Armenian Sister💋Dream Of India Is Perfect 4U, & @BobMackie at his best,” Cher raved on Twitter Saturday morning, as Kardashian replied, “I love you so much!!!”

This isn’t the first time Kardashian has dressed up as Cher. The mother of two posed in a Cher-inspired photo shoot for Harper's Bazaar Arabia -- which earned praise from Cher herself.
