WATCH Brad Pitt Confronted on Red Carpet

He's at it again.

Vitalii Sediuk, 25, was arrested Wednesday night after being accused of confronting Brad Pitt and touching him on the red carpet at the Hollywood premiere of the movie “Maleficent.”

And this isn't the first time Sediuk, who claims to be a Ukranian journalist, has done something like this.

Sediuk has pranked the likes of Madonna, America Ferrera (he tried to crawl under her dress at Cannes recently), Will Smith (he tried to kiss him at the "Men in Black 3" premiere, to which Smith slapped him), Bradley Cooper (he clutched onto Cooper's leg at the SAG Awards) and even Leonardo DiCaprio.

So, who is Sediuk?

The Ukraine native claims to work for "Studio 1+1," a website and channel in his native country. His YouTube videos also show him carrying a microphone bearing the channel's logo.

The Hollywood Reporter also stated that 1+1 hired Sediuk a lawyer, Anthony Willoughby, after he crashed Adele's Grammy win last year, where he attempted to accept the award for her and crash her acceptance speech. Jennifer Lopez stepped in and stopped that incident.

His videos also show him interviewing Dita Von Teese, Oscar nominee Barkhad Abdi, Jared Leto, but also asking provocative questions to Ryan Seacrest and producing segments on Jon Hamm's bulge.

His style is mostly slapstick until he ups his pranks -- such as in the Pitt incident -- where he actually comes in contact and scares celebrities. Pranks with Pitt and Ferrera resulted in his arrest.

Last year, after learning he avoided jail time for his Grammys stunt, he told The Hollywood Reporter, "I’m still alive as you can see, still smiling."

On what he'll do if he starts to get banned from events like the Emmys.

"Maybe I'll report from a distance," he said.
