Uh, who could blame them?

Shia LaBeouf admits that he hooked up with Megan Fox while making the Transformers films — and he’s not sure whether or not his sexy costar was attached at the time to then-boyfriend Brian Austin Green, now her husband.

Nodding in the affirmative about a hookup with Fox, LaBeouf explains in a new Details mag interview, “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.”

Without giving specific dates or details, the 25-year-old actor (now dating Hollywood stylist Karolyn Pho) continues of the fling: “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.”

When Details asks him about Fox’s status at the time with Green, he sputters. “I don’t know, man. I don’t know. I don’t know. I don’t know,” he says, repeating “I don’t know” eight more times. “It was what it was.”

Fox, 25, wed on-and-off beau Green one year ago in Hawaii. She was famously replaced by Rosie Huntington-Whiteley for Transformers: Dark of the Moon, out next month. (Director Michael Bay and LaBeouf recently confirmed that Fox’s controversial comments about Bay, comparing him to Hitler, got her dropped from the franchise — at the direct order of executive producer Steven Spielberg.)

LaBeouf also opens up about other failed romantic entanglements. His one date with Hilary Duff was “probably the worst date either of us have ever had.”

He also fesses up to “philandering around” with former co-star Isabel Lucas. “It was sort of disastrous…Neither one of us, I think, were in love. Just sort of experimenting or whatever.”

On his ex-girlfriend Carey Mulligan, with whom he parted ways in October 2010: “I still love her…I think she’s a fu**ing awesome person and an incredible actress. We’re still pals. I wouldn’t take any of it back, and I don’t think she would either. It just ran its course.”

Megan Fox was asked by the Red Band Trailer for an exclusive interview. So here’s a video as a special appearance guest on Diablo Cody’s Red Band Trailer , Episode 104: “Crazy Like A Fox”. I realize that the caps of the episode are out of order- I apologize for that and will try and see if we can fix it. It might be the name files.

Of her recent success and being labeled an “It Girl”, Women’s Health asks Bell how she rates Megan Fox.

“I want to hate Megan Fox more than anything,” she told the mag. “We all do. But I read a bunch of her [interview] quotes, and she’s witty and smart and carefree.”

Adding, “This is the kind of girl I’d love to be friend with.”

“I love it being in a relationship” she said. “I hate being single. It’s uncomfortable. Who likes dating? I just don’t like it.”

Fox, 23, recently insisted the media keeps comparing her to Angelina Jolie because people are desperate to put her “in a box”.

“The media has to package you and sell you somehow and sell their magazines so everybody has to be ‘the new’ or ‘the next’ someone or something” she said.

“If I am not a party girl and they can’t sell me as that, and I’m not an Oscar winning actress and they can’t sell me as that, then they have to package me somehow and for some reason they latched on to the Angelina thing because I have a lot of tattoos.”

“It was a way to market me and it was a way to sell their magazines or get hits on their blogs – because it makes people uncomfortable if they are unable to put you in a box.”

On the show, The 23-year-old actress said she tries to avoid all the L.A. hotspots. Megan shared, “I don’t have a lot of fun. It is a really sceney and trendy place. It’s a very fake environment. The places that I like to hang out — there’s this particular area in Burbank where I can act out my entire fantasy life. There’s an Olive Garden, an Outback Steakhouse and Krispy Kreme donuts all within a one block radius. And one shopping center. Oh, and I love Red Lobster. I love the cheese biscuits.”
