All good things must come to pass and Jessica Simpson now knows that all too well. She and John Mayer are officially dunzo after 9 months of dating and there are a slew of theories as to what caused the break. We happen to think that Mayer, a simple guy from Connecticut, could not deal with her over the top father/manager and his insistence that she dress like a whore from the Bronx. But that's just us. Above she's with John in Hollywood, then as the hostess of the Pussycat Dolls celebration and then at Cannes where she's hawking a movie that hasn't even started filming yet. Cheese.
