LOS ANGELES — He kissed Will Smith in Moscow, tried to steal Adele’s spotlight at the Grammys, dove under America Ferrera’s dress at Cannes and now police say he accosted Brad Pitt on the red carpet of a Hollywood premiere.

Vitalii Sediuk’s antics have earned him a smack in the face from Smith, probation for the Grammys stunt and have cost him his job with the Ukrainian television station that up until his incident with Ferrera, gave the 25-year-old a platform to cross the line with celebrities.

Sediuk remained in a Hollywood jail Thursday, one day after police say he leaped over a fan barrier and made contact with Pitt, who was signing autographs at the premiere of his partner Angelina Jolie’s latest film, “Maleficent.” Pitt was apparently uninjured, but Sediuk’s conduct has left him alienated from supporters and facing another possible criminal case.

Ukranian TV station 1+1 fired Sediuk roughly three weeks ago, around the time he rushed Ferrera and hid under her voluminous dress at the premiere of “How to Train Your Dragon 2” at the Cannes Film Festival.

The incidents raised Sediuk’s profile and apparently emboldened him to new stunts.

“He’s not a violent individual,” his attorney Anthony Willoughby said. “He’s an easygoing young man.”

Publicist Christa Scherck, who worked with Sediuk for the past two years and helped him get credentialed for entertainment events, said she was severing ties with him after his arrest. She said she was never aware of his prank plans.

“This goes beyond pranking,” Scherck said. “This is no longer entertaining.”
