LOS ANGELES – Rock group Limp Bizkit’s frontman Fred Durst is complaining that pop princess Britney Spears is having major trouble moving on since their brief romance in January, wrote the daily Mirror.

Durst says that he and Spears had "passionate sex" at her Hollywood home after she seduced him.

Although Spears contends that the she and Durst were never romantically involved, Durst claims he has proof in the form of threatening phone messages left on his answering machine.

Durst, 32, stated to the Mirror, "She told me, ‘Fred, you better watch your back, because you’re seriously f***ed.’"

Now, Durst is threatening to post the messages on the Internet, saying, "It’s so funny, I saved them all just in case I ever need them."

Spears, 21, has made no comment on the issue as she has been out partying in New York the last few months, and maybe a little too hard.

The Mirror reported that Spears had to be carried off to the bathroom by her two friends after drinking excessively.

Spears is reportedly working on a new album, which she hopes will distance herself from her "good girl" image.
