A man has been arrested in the US for punching Brat Pitt in the face just ahead of the premiere of his girlfriend's new film.

Pitt and Angelina Jolie were walking the red carpet in Los Angeles ahead of the World Premiere of "Maleficent" when it's alleged the man jumped the fence and then began hugging and striking the actor.

Pitt was not seriously hurt during the scuffle and authorities quickly rushed in to subdue the man - who turned out to be infamous red carpet prankster Vitalii Sediuk, who got in trouble just over a week before for crawling under America Ferrera's dress at the Cannes Film Festival.

The 25-year-old Ukrainian was arrested for misdemeanor battery.
