This star just won Halloween with her amazing costume

So Jemima Khan has just won Halloween, hands down.

The star pulled out all the stops last night as she headed off to a UNICEF charity event, dressing up in an amazing gorilla and cage costume.

The 40-year-old rocked up to the event in a wooden cage, knees tucked up to her chest, while a scary giant gorilla held her captive.

Could that be any more epic?

The star had gone to a lot of effort for her special appearance, and played up to the occasion on her social media.

Tweeting pictures of the fantastic costume, the socialite wrote: “Halloween! Off to UNICEF gig for Syrian refugees….On my way in a hearse…”

And if you thought that her big entrance was just for the awaiting cameras, you would be wrong!

The star was pictured still wearing her amazing costume late into the night, sitting at her table, in her cage, while chatting to other guests!

Jemima wasn’t the only one to put in the effort for London bash, with actor Hugh Grant showing up in a goat mask, and Guy and Rocco Ritchie dressing up as Breaking Bad characters Walter White and Jesse Pinkman.

Well done guys, amazing!
