A sex tape has reportedly surfaced -- allegedly featuring Jon Gosselin's reported mistress Deanna Hummel, but several sources say it's not her in the video.
Someone claiming to be Deanna's ex-boyfriend is reportedly shopping the clips online.
Meanwhile, reality mom Kate is standing by her man. She told the "Today" show this morning, "I'm very hesitant to believe any of it," adding, "We're dealing with it privately."
The new season of "Jon and Kate Plus 8" is set to debut May 25 on TLC.
