Simpson Back With Cook

Jessica Simpson might be dating Dane Cook again. The two started dating during filming of that piece of trash movie "Employee of the Month." They split up and Jessica began dating John Mayer. Well, now she's over his ass.

Jessica and Dane were caught "canoodling" at Prince's concert last weekend. A source said, "They were laughing, joking and hanging out. They practically spent all night together, dancing and touching each other."
