Keeping her Dukes Body... According to Us Weekly Jessica still works out 4 days a week, still does squats during every workout, and is still on the South Beach Diet.
However, My boyfriend's roommate's girlfriend's roommate is a waitress at Pastis (9 9th ave. at little west 12th street) and waited on Nick Lachey and Jessica simpson tonight! She ordered Fried chicken and French Fries and a michelob light ultra. She and Nick are obviously still together and apparently taking a break from the south beach diet.
