Joanna Krupa rocked it as Sandy from Grease in an amazing Halloween costume at George Clooney’s annual Casamigos 70’s inspired party.

Wearing the iconic black leather outfit, which Olivia Newton-John at the end of the 1978 film, Krupa really nailed it with her curly blonde hair and red shoes.

The star-studded event was held on the famous Sunset Strip in Hollywood, Los Angeles with Amal Clooney and Cindy Crawford dressing as Disco Divas in their sparkling outfits.

Casamigos invaded the Sunset Strip last night with a ‘70s-themed Halloween party for 500 guests that included Hollywood’s elite, industry tycoons, rock stars, athletes and top influencers.

George Clooney, Rande Gerber, and Mike Meldman’s highly-coveted event completely transformed the venue into a ‘70s discotheque.
