Radar claims to have a 10 year-old tape of Chelsea doing the nasty with some guy that has a thick British accent.
Chelsea claims she made it as a funny skit for her comedy reel and has been "showing off at birthday parties."
Chelsea says someone tried to call her lawyer a while back and sell the homemade tape she made back to her for a million bucks. Her response? "Nayy, I'm not worth it!"
Of course the video isn't available online for us to view, so you're just going to have to check out what she says about the video and judge for yourself!
