She's Like Janet Jackson

Jessica Simpson is such a yo-yo dieter. That’s not necessarily the healthiest of things, but so many of us do it.

The singer and wannabe actress recently got into tip top shape for her latest film, Major Movie Star.

Well, that phase of being super fit didn’t last very long!

Jess unveiled a curvier and much more normal body at the 2007 ACE Awards in NYC on Monday night.

Keep the curves!
