JSIMPSON062107_01.jpgJessica Simpson JSIMPSON062107_08.jpgNever leave the house without your handbag, ESPECIALLY when going to the gym. At least, that's a rule Jessica Simpson follows, seen heading off to work out that body even more. She's not looking quite as, er, chest-intensive here, but look how friendly she is to everyone, waving and all. A couple celebrities could learn to be just as polite. (*cough*Avril Lavigne*cough*) The eldest Simpson sister isn't responding to questions about the John Mayer/Penelope Cruz situation... although we can't help but wonder who would win in a cat fight between her and Penelope. Probably Jessica with all these training sessions at the gym!
