Grease legend Travolt was pictured wearing a clingy peach shirt dress with a red belt, and a blonde wig tied in a ponytail.

The Saturday Night Fever and Pulp Fiction star finished the look with a necklace and sparkly earrings, and spoke in a high-pitched voice.
Other guests at the party in Los Angeles were amazed when he turned up in the bizarre outfit.
