Jessica Desperate Simpson has reportedly hooked up with John Mayer yet again:
. . . an insider reveals that, in a state of desperation and loneliness, she’s been secretly hooking up with her ex John Mayer, who unceremoniously dumped her in 2007 after they dated for a year. “They’ve always had an amazing connection,” a business associate of Jessica’s tells In Touch. Ignoring her friends’ warnings that the notorious player will just use her and then break up with her again, Jessica has jumped headfirst into a relationship with the singer now that she and Tony, 29, split. “Jessica is kidding herself that her and John stand a chance,” says a source.
