Alan Cumming has praised Shia LaBeouf for making a "good recovery" after he famously disrupted his Broadway performance of Cabaret.

Former Transformers actor Shia pleaded guilty to disorderly conduct following the incident at the show, which his publicist said stemmed from an alcohol problem.

Now Alan, whose performance was disrupted by Shia's antics, has told Conan O'Brien's US talk show: "He was really messed up... He was just wasted, and he was wasted from the second he walked in."

"So there was an atmosphere. When I went downstairs to start the show, everyone was freaking out because there was someone who seemed to be a crazy person, shouting and stuff."

Alan had to walk into the audience at one point during the performance.

"As I walked past him... he, like, whacked me, and then other things, he was smoking," he said.

But the actor added: "We have all done things where we have been out of it and messed up. Not everyone has to deal with it on such a worldwide scale so I thought he made a good recovery!"

And he said of being grabbed by Shia: "He did say the reason he did it is I was the sexiest man he had ever seen!"
