The owner of an RV dealership sued by Taylor Lautner over a customized vehicle challenged the ” Twilight ” star Monday to use his muscles instead of his lawyers to resolve the case.

Brent McMahon, who owns McMahon’s RV in Irvine, Calif., offered to compete in a push-up contest to settle the breach of contract lawsuit that Lautner filed Aug. 23 claiming the dealership failed to deliver a $300,000 RV on time for use as a dressing room on the set of the actor’s latest film.

McMahon and his attorney denied wrongdoing and said they will vigorously defend the case in court if Lautner, 18, doesn’t accept the challenge.

The dealership said Lautner’s camp had sought a $40,000 settlement to resolve the case, leading to the unorthodox proposal by McMahon. The 47-year-old businessman said if he won the contest, he would donate the settlement money to Children’s Hospital of Orange County .

Lautner’s attorney Robert Barta declined comment, citing the pending lawsuit.

Lautner’s lawsuit claimed McMahon’s failed to complete the customized RV on time, and it needed additional work after it was delivered.

It was unclear what upgrades Lautner sought. McMahon said the vehicle was given a custom paint job.

Lady Gaga has a lot of followers on Twitter — the most in the world, in fact. Until very recently this title was held by Britney Spears, but Gaga’s follower count has finally surpassed hers. How symbolic! As of this writing, Lady Gaga has 5,741,164 followers, while Spears can only boast a trifling 5,703,531.

Lady Gaga celebrated her historic achievement with an amusing YouTube clip “sent while changing backstage at The Monster Ball in Tacoma.”

More.

A fuming Hal Steinbrenner informed Yankee Stadium executives that Lady Gaga is permanently banned from the team’s clubhouse after her boozy antics — including swigging whiskey and repeatedly fondling her boobs — during a visit to the house that Ruth built Friday night, sources told The Post.

The songstress and two girlfriends sauntered their way into the Bombers’ clubhouse — without team approval — and hung out for 30 minutes after the team lost to the Mets.

She met six players — including Alex Rodriguez and Robinson Cano — while the “Poker Face” singer kept slurring her words trying to say how much she loved the Yankees and how thrilled she was to be inside the exclusive area, sources said.

Lady Gaga’s booze-swilling and breast-feeling were too much for Boss Jr. Hal Steinbrenner, sources said yesterday.

Gaga, drinking Jameson Irish Whiskey, was wearing a Yankees jersey half-unbuttoned, exposing her black bra, fishnet stockings and a bikini bottom.

But apparently she didn’t think that was enough to catch the players’ eyes, so she kept groping her chest over her jersey.

If the British tabs are to be believed, splitting with his Canadian girlfriend is the reason England’s goalie dropped the ball at the World Cup.

The papers are pointing to Elizabeth Minett, a leggy Toronto-area model as a possible reason for goalie Robert Green fumbling a routine catch that allowed the U.S. to tie the match on Saturday.

Minett is a 23-year-old lingerie model who was involved with Green, but split with the goalie before the World Cup.

U.K. tabloid The Daily Mirror says Green is “apparently devastated” after parting ways with Minett.

The paper does, however, quote Green’s agent saying the split has not affected the goalie’s focus on the game.

According to the Daily Mail, the pair met two years ago when Green’s English Premier League team, West Ham United, was in Toronto playing in the 2008 Major League Soccer all-star game.

The paper says the couple lived together in a London apartment until about a month ago, when the relationship ended, leaving Green apparently down in the dumps.

Earlier, Minett had told a British paper she was going to cheer Green on in South Africa, and even had plans to speak to him in French so the couple could have some privacy.

Green has since apologized for his blunder saying the fumble made him even more determined to play again “to right the wrong.”

Minett, who graduated from the University of Waterloo with a degree in economics, currently works for Elite Model Management.

In addition to modelling, the blonde, five-foot-10 Minett has starred in pop videos for U.S. pop star Hilary Duff.

Oh, and something about Twilight:

As expected, Summit Entertainment confirmed last night that it will release Breaking Dawn, the final installment of The Twilight Saga, in two parts. Production will start this fall with the first movie set to release Nov. 18, 2011; no date was announced for the second film. Bill Condon will direct both movies, and Robert Pattinson, Taylor Lautner, Kristen Stewart, Billy Burke, Peter Facinelli, Elizabeth Reaser, Jackson Rathbone, Nikki Reed, Ashley Greene, and Kellan Lutz will all reprise their roles. Breaking Dawn is a movie adaptation of the fourth book in Stephenie Meyer’s Twilight series. The third movie, Eclipse, releases June 30.

These are actual shots of 50 Cent on the set of Things Fall Apart where he dropped over 50 pounds to play a football player diagnosed with cancer, according to ThisIs50.com:

He dropped from 214 pounds to an astonishing 160 with a liquid diet and three-hour-a-day treadmill walks for nine weeks.
“I was starving.” Now he’s back on tour and says, “I’ve been eating. I’ll be back in shape in no time!”

Christina Aguilera has canceled her 20-date summer tour, which was scheduled to begin in July.

Live Nation, the tour’s promoter, released the following statement:

“Christina Aguilera’s summer tour has been moved to 2011 due to prior commitments that the singer had made to her film, ‘Burlesque,’ and to the promotion of her new album, ‘Bionic.’ The singer felt she needed more time to rehearse the show and with less than a month between the album release and tour dates this wasn’t possible.”

Could poor ticket sales be the real reason?

“Not Myself Tonight,” the first single off Christina’s new album, charted at a disappointing 23. The video for the song was widely panned and regarded as an oversexed Gaga ripoff.

Christina’s new album will be released June 8 but has already been leaked in full. ‘Bionic’ is her first album since she took time off to have her son, and she has been working on it since 2008.

‘Burlesque,’ a musical costarring Cher, is due out in November. The singer recently posed nude for German GQ.

On Transformers:

“When I saw the second movie, I wasn’t impressed with what we did. There were some really wild stunts in it, but the heart was gone.

We got lost. We tried to get bigger. It’s what happens to sequels. It’s like, how do you top the first one? You’ve got to go bigger. Mike went so big that it became too big, and I think you lost the anchor of the movie. … You lost a bit of the relationships. Unless you have those relationships, then the movie doesn’t matter. Then it’s just a bunch of robots fighting each other.

Wait, he’s only finding fault in the Transformers sequel? That’s like McDonald’s only apologizing for your second bite of a Filet-O-Fish–as if that first tentative nibble at the hard corner without cheese was any better. But still, at least this is a step towards healing (until Transformers 3 tears off that scab).

On Indiana Jones and the Kingdom of the Crystal Skull:

I feel like I dropped the ball on the legacy that people loved and cherished. You get to monkey-swinging and things like that and you can blame it on the writer and you can blame it on Steven [Spielberg, who directed]. But the actor’s job is to make it come alive and make it work, and I couldn’t do it. So that’s my fault. Simple.

We [Harrison Ford and LaBeouf] had major discussions. He wasn’t happy with it either. Look, the movie could have been updated. There was a reason it wasn’t universally accepted.

I’ll probably get a call [from Spielberg]. But he needs to hear this. I love him. I love Steven. I have a relationship with Steven that supersedes our business work. And believe me, I talk to him often enough to know that I’m not out of line. And I would never disrespect the man. I think he’s a genius, and he’s given me my whole life. He’s done so much great work that there’s no need for him to feel vulnerable about one film. But when you drop the ball you drop the ball.
