Lauren Conrad's past with Jason Wahler continues to haunt her. Their relationship was full of bad decisions, but Jason is denying that one of those involves the creation of a sex tape between him and ex-girlfriend Lauren. Wahler told Us Weekly magazine, "I do not have a sex tape of Lauren Conrad and one does not exist."

This denial comes in reaction to a recent visit that Spencer Pratt and Heidi Montag had on The Tyra Banks Show. Spencer told Tyra, "I know for 100 percent fact it did exist - 1000%!"

Whoah, that's a lot of percents. However, Heidi did admit that neither she nor Spencer have actually seen the tape themselves, but they are a million percent sure it's real. A billion percent, even.

Meanwhile, Lauren is trying to move on with her life with her new relationship with penis-checking boyfriend Doug Reinhardt. This woman has such stellar taste in men. She should start a match-making service.
