Hollywood prankster Vitalii Sediuk has apologised to his celebrity victims.

The 25-year-old former journalist - who scaled a barrier at the 'Maleficent' premiere to confront Brad Pitt and has previously accosted stars including Bradley Cooper, Leonardo Dicaprio and Will Smith at red carpet events - insists he has changed his ways and now plans to leave Los Angeles for good to launch a modelling career in London.

He told the Hollywood Reporter: ''Basically, I'm changing my life. I would like to thank Hollywood for having me this two years and a half. It was an experience that taught me a lot in life. Most importantly, I would like to say sorry for celebrities that had to deal with my stunts and thank them for being tolerant to me all this time.''

However, the Ukranian prankster insisted his controversial antics - including attempting to put his head up America Ferreira's dress - have often been misunderstood and were always meant in good fun.

He added: ''The motivation behind all my pranks was always positive even when some of them went wrong and were not understood by the public.

''I came to the decision to move overseas, but there's some part of me that will stay in this city. I know you will not miss me.''

After his encounter with Brad in May, Sediuk was sentenced to 20 days of community service and ordered him to stay 500 yards away from all award shows, entertainment events and red carpets.

Additionally, Brad and his fiancee Angelina Jolie also took out a restraining order against him.
