No more John Mayer, no more brunette locks? We can’t say for sure that Jessica Simpson‘s breakup triggered her going back to blonde, but who hasn’t changed up their look post-relationship trauma? Wearing a second-skin Herve Leger gown, Jessica showed off her new (old) hair while promoting her upcoming movie Major Movie Star at the Cannes Film Festival. We thought at least she would transition her locks slowly back to blonde, but — boom! — she’s back to her old look just like that. We think the dark honey blonde suits the star, but what do you think? Tell us: Do you like Jessica as a blonde? Or did you like her better as a brunette?
