Heidi Montag, Karissa Shanon made a lesbian sex tape

The Heidi Montag sex tape story would be a lot hotter if every person involved with it didn’t have a long and well documented history of attention whoring and/or making up fantastic stories to get themselves in the headlines.

We’re told not too long ago Spencer was at the Malibu house he once shared with Heidi … moving out some of his stuff.  Sources tell us Spencer came upon a camera with XXX video of Heidi and (Playmate Karissa Shanon).
As for Karissa — she tells us such a tape does indeed exist, but she’s not convinced Spencer really has it. Karissa says if the tape ever sees the light of day, she’ll sue.

If true, it seems this sex tape is really gonna come back to haunt Heidi. People always laugh at me because I don’t have any sex tapes, or a girlfriend, or a girl willing to have sex with me, or go on a date with me, or talk to me, or make eye contact, but look how all that backfired on Heidi. Who’s laughing now!
