Brit insiders are calling foul on the pop star ater a person claiming to be Britney Spears posted several messages on Myspace confirming a third pregnancy and then a miscarriage. Tabloid spies claim the singer may have started the third pregnancy rumor herself!

“It could be Britney is just messing with everyone by writing these things,” a friend tells Star.

“She loves to play games on people. But who would even make up this kind of stuff? It’s sick, and this isn’t the Britney we used to know.”

“If this is really her who’s writing these things, she’s even more crazy than we thought. Why is she out partying instead of staying in and grieving? Nobody really knows what’s going on in Brit’s head these days.”
