Playboy playmate Karissa Shannon confirmed Friday that there is indeed a sex tape featuring herself and 'The Hills' star Heidi Montag, RadarOnline.com reports. And though she admits to the tape's existence, she claims Spencer Pratt stole her camera that contained the scandalous video.

The playmate told RadarOnline that the video is just of her and Montag. "There is a sex tape of me and Heidi," emphasizing that Spencer was not around when they shot the video. "It's just me and Heidi, that's it," she said.

Pratt's been making the rounds the past week trying to sell the tape, including speaking with Vivid Entertainment, the porn company made famous for distributing sex tapes of Kendra Wilkinson, Kim Kardashian, and most recently, Montana Fishburne.
