Jessica Simpson and Eva Longoria were reportedly fighting because Eva was nice to Jessica’s ex John Mayer. In fact, Page Six reports:

"When her close pal Jessica Simpson got wind that Longoria was hanging with Simpson’s ex, John Mayer, the other night at Gold Bar on Broome Street, she "went nuts," said an insider. "When Jessica heard that Eva was being friendly and polite to John, she called her a back-stabber and was furious."

A rep for Simpson denies the fight, but you know Jessica is petty like that. She’s a whore, but she wants to own her guys at the same time. Fruity as a fruit cake.

There’s also a report that Jessica was told she would win an Oscar if she did a movie where she takes off all her clothes. A source said:

"Jessica is in the running for a role that, if she gets it, will put her right on the map in terms of acting. The only hitch is that the script requires a number of quite graphic scenes including a full-frontal nude scene. Jessica is so desperate to land the role and get the industry’s respect that she’s ready to go against her better judgement, and her family, by agreeing to bare all."

Everyone has already seen Jessica nude in Hollywood, except for me, so really this isn’t that much of a stretch for her. Like when she goes on blind dates, she just shows up naked otherwise she’d never make it to second or third base. The dumb blond thing is such a turn off so she’s got to pull out the big guns. Joe Simpson apparently turned down the offer for Jessica saying:

"The last script that came to us was for Jessica to be a porn star. We were promised we would win an Oscar with that. I told them, ’I think we’ll just buy a statue of a little man and keep our clothes on.’ "

Porn star acting is what Jessica does all the time, she’s perfect for that business. She probably really believed those people when they said she’d win an Oscar if she took her clothes off. It’s not that hard to get her naked. All a guy has to say is "FREE WILLIE."

Thanks to papa Joe Simpson, Tony Romo and Jessica Simpson are now banging with daddy’s approval. A source said:

"Joe and Tony have been friendly for a while. Joe is a huge Dallas Cowboy fan, and Tony has always had a crush on her – he even said on his Web site like a year ago that it was his dream to date her. Jessica has been in Nashville and Dallas recording her new country album. When Tony found out, he called Joe and said, ’I know she’s not dating anyone right now, can I take her out for a drink at least?’ Jessica said it was OK for Joe to give Tony her number and they hit it off. They’ve been dating for a couple of weeks now, and Jessica is so happy. She’s been texting everyone about how great he is."

Romo even joined the Simpsons in Waco, Texas, for Thanksgiving. A rep for Simpson declined to comment on her personal life but said, "She is happily recording her country album." Romo has been linked to Carrie Underwood, Sophia Bush and an unidentified Dallas brunette.

Joe also said John Mayer "has always had a crush on her." Scripted.

You know it’s a slow day when 24/Sizzler points out the fact that John Mayer wears a gigantic size 13 shoe. You know what they say about men with big feet…

They’re big douche bags. And ya know what they say about women with big feet…

They’re big whores (like Paris Hilton).

While John Mayer is busy going green, Us Magazine is reporting that his ex, Jessica Simpson, is busy being green…with envy.

A source close to the singer tells Us Simpson is “really jealous” that ex John Mayer is seeing Cameron Diaz. “She had her mouth open a mile wide when she found out,” says the source. “She just freaked.”

And the way they could tell this was her mouth being open a mile wide? Have they seen Jessica Simpson before? Her mouth could fit a freight train twice on Tuesday and she shows us that in every photo she takes.

Simpson, 27, parted ways with Mayer, 29, in May after dating him on and off for seven months, and “she thinks about him all the time,” says the source. “She is so not over him.”

Meanwhile, Simpson seems to be a distant memory for Mayer, who has continued his summer romance with Diaz, 35, in NYC. Though they spent August 22 and 23 apart (he hit the gym and recorded at a studio; she shopped and then lunched at Mary’s Fish Camp), they finally squeezed in quality time in the wee hours of August 24 at hot spot Socialista. The pair — who left at 4 a.m. through different exits — “were very cozy,” says a witness.

But what, pray tell, of the rumored romance between Cameron and Bradley Cooper? E! reports:

Sources close to Bradley and Cameron Diaz tell me that the two have been dating the past couple weeks. Pretty adorable, no?

Bradley’s rep insists that it is "not true" that the two are dating. However, insiders tell me that Cameron and Bradley have been busy sending flirty text messages to each other throughout the day and spending quite a bit of time together.

I can only guess that Cameron must be good in the sack cuz that face could be most people’s butt double.

TMZ is speculating that John Mayer and Mandy Moore may be the latest musicians (cough) to couple up.

The "Chocolate Rain" singer was spotted out in SoHo yesterday having lunch with Mandy Moore, who was in town for the premiere of her new movie, "Dedication."

The frumpy pair (is that a potato sack she has on?) would make sense as a couple — she likes funny guys with good musical taste (Zach Braff) and he likes women.

However, Us Magazine has reported that Mandy Moore says that they have been "friends for years."

Just in case, it’s always handy to come up with one of those annoying couple monikers.  Johndy?  Maymoore?  Or perhaps just "Milk Toast."
