A very pregnant Ashlee Simpson-Wentz spent her first trimester gleefully stocking up on fried foods and heavy starches, a pal of the pop songstress tells Life & Style.

“Ashlee’s problem is that she believes she’s eating for two,” says an insider, who adds that the star has already ballooned 22 pounds only halfway through her pregnancy. “It’s as if she wants to eat everything in sight….She likes anything with chocolate.”

From deep-fried beef taquitos to fully-loaded burgers, Ashlee is enjoying a pregnancy filled with junk food, spies claim:

“She said that since getting pregnant, she’s been craving fried food,” according to another celebrity mole.

Ash has also become a sucker for green olives, says hubby Pete Wentz.

But while Ashlee’s having fun packing on the pounds for her baby girl, expected this October, the mother-to-be isn’t excited about the transformation pregnancy could cause for her figure:

“She knows the minute she gives birth, she’s going to have to work really hard to take off the weight.”
