Shia LaBeouf Apologizes For His Behavior, Says Jail Made Him Snap Out Of It

Shia LaBeouf is really sorry, and he's not just saying #IAMSORRY through performance art this time.

LaBeouf stopped by "The Ellen DeGeneres Show" on Friday to promote his upcoming movie, "Fury," but not without addressing the bizarre stunts that landed him in the tabloids earlier this year.

"I went through like an existential crisis ... I had some hiccups, some judgement errors," LaBeouf said.

After recalling the "Nymphomaniac" premiere -- where LaBeouf wore a paper bag over his head reading "I am not famous anymore" -- and his #IAMSORRY exhibit, where he invited people to read mean tweets about him and even use an "Indiana Jones whip" or pliers on him, the actor explained that he has something in common with the cyber bullies who sought a reaction from him.

"I got in this [entertainment] industry because I had this void. I'm a kid of abandonment and I thought somehow being a good actor would fill that void. I think we suffer from the same thing, which is just a lack of attention and love," he said.

The star told DeGeneres that his 24-hour stint in jail is what eventually snapped him out of his behavior, and apologized for spitting on a cop, which triggered his arrest.
