When did sex tapes become a trend? According to sources close to Perez Hilton, MTV reality star Lauren Conrad allegedly has a sex tape with her ex Jason Wahler.

“Jason is trying to sell the video before he goes to jail,” a source close to Wahler said. “LC will lose her mind when she finds out!”

Lauren’s reps at PR firm Rogers & Cowan are literally in a frenzy trying to get to the bottom of this. Some doubt the existence of the tape, claiming its just a PR move…but I guess we’ll have to wait and see.

“Lauren tried to break into Jason’s apartment to get the tape,” says a mutual friend of the pair. “She was practically stalking him and calling non-stop until he finally agreed to give her the video.”

“They edit around the show to make Lauren look like a goodie two shoes on The Hills, but she’s hardly a saint,” says an insider on the show. “LC is gonna pop more Adderal then she usually does when she finds out that news of the sex tape was made public.”
