Jessica Simpson Weight Gain . . .

Once renowned for her famously cut abs and sculpted legs, it seems that country singer Jessica Simpson has eased up on her fitness regimen a bit.

The former “Newlyweds” star and ex-wife of Nick Lachey showed off her noticeably fuller curves at the Radio 99.9 Kiss Country’s annual Chili Cookoff in Florida Sunday.

Donning mom-jeans, a tight black tank top and a muffin-top-inducing leopard belt, the songstress’ appearance left the gossip-world abuzz.

Is Jess preggers? Did she gain sympathy weight for sis Ashlee (who just had a baby with hubby Pete Wetnz)? Is it all a ploy to get her on the cover of a magazine? Or is it, more likely, that the star has been eating the same diet that her Dallas Cowboys quarterback boyfriend Tony Romo does?

JESSICA GIVES SOME ANSWERS: in (entertainmenttonight.com)
Jessica Simpson admits she has been eating too much because she is so worried that she will get bad reviews whilst promoting her new country album.

The former pop star confessed she is a nervous eater and that she is terrified her country music career will flop.

“I’m a nervous eater and this tour has made me a nervous wreck,” she tells the National Enquirer.

Jess has recently been pictured with a bit more meat on her bones and has been wearing baggy clothing, prompting the inevitable speculation that she may be pregnant with Dallas Cowboys boyfriend Tony Romo.

But the Dukes Of Hazzard star insists a baby is not the reason for her changing appetite.
