Brad Pitt's Attacker Speaks to ET About His Red Carpet Pranks (VIDEO)

Watch ET's interview with Brad Pitt's attacker.

Notorious red carpet prankster Vitalii Sediuk struck again at last night's Hollywood premiere of the Disney fantasy-adventure film Maleficent by attacking Brad Pitt as he walked the carpet. But last year, ET's Rob Marciano spoke with Sediuk in the wake of his crashing a speech by singer Adele at the 2013 Grammy Awards and we've got the video!

At the 55th Grammy Awards, Sediuk managed not only to get inside the Los Angeles venue, but also did interviews with celebrities on the red carpet and also sat in the second row of the venue right behind Justin Timberlake.

The 25-year-old Ukrainian self-described journalist -- who was quickly detained by security after Wednesday's incident and arrested by police and booked for misdemeanor battery -- has of course made headlines before for forcing himself on other celebrities at various red carpet events around the world.

Just two weeks ago, Sediuk was dragged off a red carpet at the Cannes Film Festival after he burst onto the scene and crawled under the dress of actress America Ferrera at the How to Train Your Dragon 2 premiere.

Last January, he worked his way onto the red carpet for the Screen Actors Guild Awards and grabbed the legs of actor Bradley Cooper, and in May 2012 Sediuk also received a slap from Will Smith when he kissed the star on the red carpet.
