Jason Wahler: Spencer Pratt Sucks, Lies

Jason Wahler is speaking out against Spencer Pratt's recent claims on national TV that a Lauren Conrad sex tape exists.

"I do not have a sex tape of Lauren Conrad and one does not exist," Wahler said in a statement. "Spencer Pratt is lying again to get attention.

"Lauren is my friend," said Wahler, LC's ex, who's battled a long list of legal problems. "And it is insulting to her to suggest this."

On Tuesday's Tyra Banks Show, Spencer Pratt declared, "I know for 100 percent fact it did exist - 1,000 percent!"

Spencer Pratt and Jason Wahler: The battle continues.

Pratt's girlfriend, Heidi Montag, also claimed the video is:

"Not a rumor. From what I have heard from confirmed sources... her ex-boyfriend [Jason Wahler] was going around trying to sell it."

Banks then asked Heidi Montag, if she hadn't seen the tape, how could she be so sure it existed?

"Well, I mean, I am not sure she has it anymore... but from what I've heard... I am not really allowed to elaborate."

Very convincing argument right there, Heidi. What else would you expect from the biggest media whore in Hollywood after Ashlee Simpson?
