The Ukrainian TV prankster who gatecrashed Adele's big Grammy Awards moment last year struck again at the Screen Actors Guild Awards on Saturday.
Vitalii Sediuk threw himself around Bradley Cooper's legs on the red carpet at the Hollywood event.
The 25-year-old Ukrainian journalist somehow made his way onto the red carpet and greeted Cooper with a handshake as he arrived. But the encounter soon turned awkward when Sediuk got down on his knees and hugged the actor's thighs as Mandy Patinkin and Michael Pena looked on in surprise.
Photos of the incident show the Oscar nominee trying to laugh off the stunt by attempting to pull Sediuk back to his feet, but he needed a little extra help from Pena to free himself from the man's grip.
Cooper has yet to speak out about the incident, which occurred seven months after Sediuk was sentenced to three years probation following his arrest last February for trespassing at the 2013 Grammys.
Sediuk hit headlines after taking the microphone from shocked presenter Jennifer Lopez as Adele made her way to the stage to accept her Best Pop Solo Performance Grammy.
The prankster also upset Will Smith at the Russian premiere for Men in Black 3 in 2012, when he attempted to kiss the Hollywood star, only for the actor to slap him.
