In The Hills story that wouldn't die, Spencer Pratt is sticking to his story that the Lauren Conrad sex tape existed, even if it doesn't exist right now.

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

But Spencer Pratt, who said on the Tyra Banks Show late last week that he's 100 percent sure the tape existed, countered: "Jason's statement couldn't be more transparent. Notice how he uses present tense, 'I DO not have a sex tape... one DOES not exist.' We all know that it existed, that he tried to sell it and is now covering up to make himself look better."

Do you believe Spencer Pratt or Jason Wahler?
