Kim Kardashian’s Halloween costume has got the only seal of approval that matters.

The 37-year-old donned a stitch-perfect Cher costume on Friday night that amazed everybody – including Cher herself.

After Kim and BFF Jonathan Cheban arrived at Rande Gerber and Cindy Crawford’s Casamigos annual costume party, the 71-year-old icon joined the praise on Twitter.

Kim was delighted to have received a blessing from the legend herself.

The night before Kim looked sensational as she bared her abs in a flowing yellow co-ord that flattered her tanned complexion.

The Keeping Up With The Kardashians star channelled the iconic singer in bohemian sheer flared trousers, matched with a crop top boasting long, trailing sleeves.

Kim and Cher of course also share an ethnicity as well as their good looks, being arguably the two most famous Armenian-Americans on the planet.

The pair had hinted at their costumes via Instagram, as Kim scanned her figure while Cher’s Believe played in the background.

Casamigos Halloween Party was hosted by George Clooney, Rande Gerber and Mike Meldman, the co-founders of the brand that recently sold for $1billion.
