Breakup Alert

UPDATE: Jessica Simpson and John Mayer have officially split. I am sure it had nothing to do with Papa Joe's comments the other day about their relationship. I think Papa Joe needs to but-out of her personal life!
Do you think she will blame Operation Smile for this one?

A close source to the couple tells PEOPLE, "She's kind and sweet and he's a terrific guy, but it's safe to say it has run its course."

And there you have it.
