Are Jessica Simpson and John Mayer done? A little birdie has revealed that:

”They broke up Sunday night, but who knows what the future will hold,” says a Simpson source. “This is the twelfth time they’ve broken up. Their relationship is volatile. Last week they felt better than ever. This week, things are rocky. Who knows what the future will bring.”

and has left Jessica asking

“Hmm, why does he only get back with me for upwards of 15 minutes at a time…?”

Poor Jess, I hope she gets off this emotional roller coaster soon!
