There is somebody who thinks Jessica Simpson's body is no longer a "wonderland" he wants to explore. The singer and her boyfriend, John Mayer, have reportedly broken up.

According to PerezHilton.com, the split happened this past weekend after some trouble between the lovebirds began to surface.

John was already said to be living up his life as a single man when he hit the nightclubs on Thursday night. Sources tell the celebrity blogger that "[John] was f***ing drunk off his ass and was spending a lot of time with an ugly brunette that was not Jessica Simpson."

Earlier this week, Jessica's dad had praised his daughter's relationship with the music "legend," telling PEOPLE magazine that "If Jessica is in love, I love the things she is in love with."

But I guess the man who claims he knows what's best for his daughter has now come to realize that she wasn't in love as much as he thought to begin with.
