Ashlee Simpson is in Bikini Shape

Ashlee Simpson is red hot on the June 2008 cover of Shape.

“I never thought I’d be on the cover of a magazine in a bikini,” the 23-year-old singer tells the mag. “I try to listen to what my body craves. Sometime it tells me to eat more fruit, but sometimes it tells me to eat Skittles!”

When asked how she says in such great shape, Ashlee said, “Exercising makes me feel stronger and sexier. It just makes my whole day better. I have more energy to perform, my head is clearer—which helps me write my lyrics—and I sleep better. What more can you ask for? …I love it when my arms are toned, so we use weights to target them—and we do lunges to give my small butt more shape.”

Added the future Mrs. Pete Wentz, “Engaged life is fantastic. We are having a blast and are definitely thrilled.”
