Shia LaBeouf Suits Up, Talks Fighting Michael Bay on ‘Letterman’ (VIDEO)

Shia LaBeouf sure cleans up nice! The Transformers star changed out of his trademark vintage t-shirt and skinny jeans for a handsome well-tailored suit when he made an appearance on The Late Show with David Letterman last night.

Shia remained true to his bad boy roots by wearing a non-traditional skinny suit with a light gray shirt. It may be different from what he normally wears but you can’t deny that Shia looks hot in a suit!

Once inside, Shia revealed to David Letterman that he has butted heads with Transformers director Michael Bay quite a few times.

“These movies are hard to make,” Shia told Dave when he asked if had ever gotten into a fight with Bay. “[He’s never come at me] with any malice but he’s my teammate, even teammates scream at each other.”

Watch a clip from the interview below.

Shia is full of revelations about life on the Transformers set. The former Disney star revealed to Details magazine that he had hooked up with co-star Megan Fox while they were filming together.

“Look, you’re on the set for six months, with someone who’s rooting to be attracted to you, and you’re rooting to be attracted to them,” Shia tells the magazine. “I never understood the separation of work and life in that situation. But the time I spent with Megan was our own thing, and I think you can see the chemistry onscreen.”

Shia and Megan were long-rumored to be hooking up on the Transformers set during “off” periods from Megan’s relationship with now-husband Brian Austin Green.

Megan isn’t the only co-star that Shia has hooked up with – the actor dated Wall Street 2 co-star Carey Mulligan after the two met on set.
