Vitalii Sediuk told the Hollywood Reporter he was trying to hug Pitt when the incident occurred at the El Capitan cinema in Hollywood on 28 May, and denies striking the star. Sediuk, a former TV personality in his native Ukraine, was subsequently arrested on the red carpet and is now serving a 17-day community service sentence for battery and unlawful activity.
"I can't feel sorry for Brad Pitt," said Sediuk, who was photographed wearing a T-shirt adorned with the image of a young Pitt. "He has everything you can imagine. And I'm cleaning toilets? Sorry, but excuse me."
Sediuk also revealed that his attempt to peer up America Ferrera's skirt at the Cannes film festival a few weeks earlier might have turned out far worse.
"Actually, I was going for Cate Blanchett," he said. "I thought, 'OK, Cate Blanchett is a major star; she'll have the bigger dress. The police asked me, 'Did you see anything?' And I said, 'No, because the dress was many layers'."
Unlike Ferrera, the star of How to Train Your Dragon 2, Blanchett happened to be wearing a sheer Givenchy skirt at the premiere. "It would have been a sexual harassment [charge]," added Sediuk.
As part of his community service at Griffith Park in Los Angeles, Sediuk is cleaning toilets and removing weeds. His exploits, which include attempting to kiss Will Smith, groping Bradley Cooper and grabbing Leonardo DiCaprio, have lost him his job at the Ukrainian TV station 1+1 and left him facing the threat of a ban from future Hollywood red carpet events. Sediuk will attend court again on 8 July.
Following the incident Pitt, 50, told People magazine he was at the El Capitan with his partner Jolie and five of their children when the prankster managed to jump the barrier.
"I was at the end of the line signing autographs, when out the corner of my eye I saw someone stage-diving over the barrier at me," he said in a statement. "I took a step back; this guy had latched on to my lapels. I looked down and the nutter was trying to bury his face in my crotch.
"I don't mind an exhibitionist," Pitt added. "But if this guy keeps it up he's going to spoil it for the fans who have waited up all night for an autograph or a selfie, because it will make people more wary to approach a crowd. And he should know, if he tries to look up a woman's dress again, he's going to get stomped."
