Playboy playmate Karissa Shannon is admitting to having a sex tape with Heidi Montag, but claims Spencer Pratt stole it from her!
"There is a sex tape of me and Heidi," Karissa told Radar Online on Thursday. "It's just me and Heidi, that's it."
Spencer has been threatening to release the sex tape that he supposedly found of his estranged wife Heidi and Karissa.
But Karissa claims Spencer stole the video camera with the footage and doesn't own the tape.
"Me and Heidi were hanging out at her house in Malibu and he came over to pick up some stuff and he 'accidentally' took my camera," Karissa explained. "I talk to Heidi every single day and I tried to be there for her when she was going through her divorce, but now it's starting to affect my life."
"Spencer had no right to steal my camera," she said. "There are other things on there that I don't want to come out, including the video of me and Heidi."
"I don't know, I just wish I'd done it the sex tape with Lindsay Lohan," Karissa added. "At least it wouldn't be on the market right now!"
