Shia LaBeouf may be a major movie star, but that doesn't mean he has to run a comb through his hair before leaving the house!

The low-key actor has been enjoying a successful summer with Transformers: Dark of the Moon, which recently surpassed the $900 million mark worldwide, and is rapidly on its way to earning a billion dollars by the end of the summer.

But the 25-year-old is kissing the robot franchise goodbye, for now, and is gearing up to star in the Robert Redford-directed film, The Company You Keep. LaBeouf will play a young journalist hunting for a former Weather Underground militant (Redford) who has been on the run from the FBI for decades, according to Variety.

Company is set to begin filming Vancouver this September.

Transformers: Dark of the Moon the third installment in the action series by Michael Bay, pulled in $30 million Friday, putting its total domestic haul to-date at nearly $96 million.

Dark Moon, starring the new-to-the-trilogy Rosie Huntington-Whiteley and the series' star Shia LaBeouf, got a jump on the holiday weekend, opening Tuesday night in special 3D sneaks. The film's foreign box office is impressive as well, grossing $66 million through Thursday for an international total of at least $161.7 million, according to The Hollywood Reporter. The industry publication estimates the film could take in as much as $370 million, worldwide, by end-of-day Monday.

Meanwhile, the new Tom Hanks-Julia Roberts film Larry Crowne pulled in an older crowd, with 71% of the audience over 50!

On the flip side, Selena Gomez's Monte Carlo, grossed $3 million on Friday and 61% of its audience were under 25; 82% were female. The movie cost $30 million to make and is expected to bring in a low-teens figure by the end of the holiday weekend. Let's hope it will! Reviews, for the most part, have pitched it as a fluffy teen flick -- that said, it's that teenage disposable income so many marketers try to reach so maybe with Selena's name on it, the film can do just that!

Shia LaBeouf stopped by Jimmy Kimmel Live to promote his latest film Transformers: Dark of the Moon, but talk quickly turned to his encounter with the beautiful Selena Gomez backstage at the MTV Movie Awards.

Turns out Selena has a huge crush for Mr. LaBeouf! Hmm...what does Selena's beau Justin Bieber think about this one?

Shia says there's nothing for the 17-year-old singer to worry about it. He also tells Jimmy about his encounter meeting the Biebs. Shia says:

"He rolls up with a huge squad of dudes ... he has to. He has this presence like Buddha or a young prince. I went up to say, ‘Hi’ and the security is like, 'Whoa, whoa' and ready to take me down. Bieber does this two-finger wave like, 'He's OK."

We have to admit, we're loving Shia's 'stache. Sexy! See more of his interview with Kimmel ... after the jump.

Shia LaBeouf made headlines Monday when Details magazine released its interview with the star, in which he revealed that he and former Transformers Megan Fox had hooked up.

It seems a day of having your name in news all over the world will spark a change of heart.

At Tuesday night's Transformers: Dark of the Moon NYC premiere, he told Access Hollywood:

"I just turned 25, and I’m learning how to edit myself and say 'no comment' now.”

Indeed.

Shia's Transformers co-star Patrick Dempsey stuck up for him, but said Shia has a lot to learn.

“He’s always very candid, that’s who he is and you have to respect that in him. He’s a young man who’s learning a great deal every day. He’s a great actor to work with… I have nothing but good things to say about him. He’s a really nice guy.”

So far, Fox has not commented on the story.

In case you missed Shia's exact words, read them after the jump.

Shia LaBeouf has given a personal, revealing interview to Details magazine, and in it he says he and Megan Fox hooked up while filming Transformers ... and she might have been dating hubby Brian Austin Green at the time.

When asked if he and Megan hooked up, Shia "nods affirmatively," says the article. Shia is quoted:

"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. 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."

And as for whether she was with Brian Austin Green at the time, here's an excerpt from the article:

"I don't know, man. I don't know. I don't know. I don't know. . . ." — repeating the phrase exactly 12 times with various intonations, as if trying to get it just right. Finally, he says, "It was what it was."

Shia also dishes the dirt on his former flames Isabel Lucas and Carey Mulligan. Read what he said after the jump!

Last week, Shia LaBeouf made some borderline disrespectful comments to the Los Angeles Times about Transformers series director Michael Bay and how he (Bay) treated Megan Fox during filming. His statements included:

"Michael, who some people think is a very lascivious filmmaker, the way he films women. Mike films women in a way that appeals to a 16-year-old sexuality. ... there was no time for fluffy talk. ... And the one thing Mike lacks is tact.”

Now, LaBeouf is backtracking. He told MTV:

"I love Mike; we're like brothers. And we have our bickering in public sometimes, but I love Michael. And he's still the favorite director I've ever worked for, and I would work with him again, and I'd do anything for him. ... no way was anything I was trying to say in malice or trying to attack Michael."

Bay is your favorite director, Shia? What about, you know, Steven Spielberg, who directed you in Indiana Jones and the Kingdom of Crystal Skull?

You're diggin' yourself deeper, Shia!

Shia LaBeouf is opening up about why he believes Megan Fox didn't stick around for Transformers: Dark of the Moon. Victoria's Secret model Rosie Huntington-Whitely replaced the brunette beauty in the summer action flick.

In a recent interview with the LA Times, Shia says:

“Megan developed this Spice Girl strength, this woman-empowerment [stuff] that made her feel awkward about her involvement with Michael, who some people think is a very lascivious filmmaker, the way he films women. Mike films women in a way that appeals to a 16-year-old sexuality. It’s summer. It’s Michael’s style.

And I think [Fox] never got comfortable with it. This is a girl who was taken from complete obscurity and placed in a sex-driven role in front of the whole world and told she was the sexiest woman in America. And she had a hard time accepting it."

As for why her relationship with director Michael Bay didn't work, Shia adds:

"When Mike would ask her to do specific things, there was no time for fluffy talk. We’re on the run. And the one thing Mike lacks is tact. There’s no time for [LaBeouf assumes a gentle voice] ‘I would like you to just arch your back 70 degrees.’”

The first full trailer for the new Transformers flick has arrived, and it's intense!

Looks like director Michael Bay opted to save any one-liners, which lighten up the action flicks, for the theater. This trailer is action sequences and hotness only -- the hotness being Shia LaBeouf, Josh Duhamel, Patrick Dempsey, Rosie Huntington-Whiteley and Tyrese Gibson.

We'll be interested to see how the pic explains the departure of Megan Fox's character (Rosie Huntington-Whiteley is Shia LaBeouf's new love interest.) Maybe she met an untimely robot death?

But, the flick is sure to have laughs because some hilarious comedians have joined this cast that weren't in the first two; see who after the jump!
