Back in June, Shia LaBeouf's bizarre behaviour made headlines once again when he was arrested for drunkenly interrupting a performance of Broadway's 'Cabarat,' where he began "acting up" by smoking cigarettes inside the building and grabbing the butts of several actors.

Over a week ago, for the first time since the incident, the 28 year-old actor explained the events that led up to his arrest while appearing on 'Jimmy Kimmel Live.'

However, the star of the Broadway show, Alan Cumming, has finally recalled what actually occurred with LaBeouf from his viewpoint during an interview on 'Conan' Monday (Oct 20th).

"He was just wasted, and he was wasted from the second he walked in," Cumming explained to the host Conan O'Brien. "So there was an atmosphere when I went down to start the show, everyone was freaking out. There was someone who seemed to be a crazy person shouting and stuff."

Cummings also confirmed that prior to his arrest, LaBeouf did grab his backside during a part of the performance when the 49 year-old actor walked through the audience.

"As I walked past him, he was at the table in the end of the row and he, like, whacked me," he said. "He did say the reason he did it is I was the sexiest man he had ever seen."

Even though LaBeouf nearly ended up ruining the entire show, and was subsequently charged with two counts of disorderly conduct, one count of criminal trespassing and one count of harassment after disrupting the play, Cumming doesn't hold any grudge.

"We have all done things where we have been out of it and messed up," he said. "I thought he made a good recovery!"
