Brad Pitt

Brad Pitt was attacked at the Hollywood premiere of Maleficent Wednesday by a man who has a history of assaulting celebrities on red carpets and during awards shows, CNN reports.

Pitt, 50, was signing autographs at the premiere when Vitalii Sediuk, 25, jumped over a barrier and hit him in the face, according to CNN. Sediuk, a Ukranian television host, was arrested on suspicion of battery.

In the wake of Wednesday's incident, Sediuk has been dropped by both his publicist and his outlet Studio 1+1, according to RumorFix.com. His publicist said when she spoke to Sediuk on Monday that he did not give her any indication he was planning another prank.

Just last week, Sediuk was arrested at the Cannes Film Festival after he dove headfirst underneath America Ferrera's dress at the red carpet for How to Train Your Dragon 2. Earlier this year, he put his face in Bradley Cooper's crotch at the SAG Awards. He also charged the stage while Adele was giving a an acceptance speech at the 2013 Grammys, and was slapped in the face by Will Smith after trying to kiss him in 2012.

Pitt was at the premiere with his partner Angelina Jolie, who stars in the title role. They continued to walk the carpet after the attack and "neither appeared to look fazed," CNN reports.
