Suki Waterhouse, Hugh Grant and Tinie Tempah party for UNICEF's Halloween ball

Celebs including Suki Waterhouse and Hugh Grant turned out on Thursday night for UNICEF's annual UK Halloween ball.

Hugh Grant arrived a simple black suit but he accessorised with an angry bull mask, while Suki wore an elaborate black cut-out dress with clown make-up.

Jemima Khan came trapped in a box, and was carried around all evening by someone in a black gorilla suit, while Tinie Tempah looked smart in a fashionable blue suit.

The ball hopes to raise vital funds to help protect Syria's children from danger. On Thursday, the UK Government confirmed it will match pound for pound all public donations for UNICEF's work to protect Syrian children.
