Sources who have seen the video tell TMZ there are several clips. The first appears to show a woman and Kevin in a club getting cozy. The tape then cuts to a bed, where you don't see the people in the bed ... but hear it creaking and someone getting slapped.
You never see Kevin in the 2nd clip. The 3rd clip shows 2 people milling around a room, one of them looks vaguely like Kevin.
We're told the person allegedly extorting Kevin has demanded payment from him to avoid the tape's release.
Sources tell TMZ a woman has allegedly demanded money from Kevin after shooting a video with him in which Kevin and the woman are engaged in "sexually suggestive" conduct. We are told it is NOT a sex tape, but looks like it is a prelude to sex. We're told that at a point in the tape when the action is the heaviest, you cannot actually see Kevin.
A rep for Kevin tells us ... "Someone tried to set Kevin up in a failed extortion attempt. As law enforcement is involved, we cannot comment further as it could affect the investigation."
