Gossip Girl star Leighton Meester sex tape shocker.
According to multiple sources, the To A Convict Born CW cutie was getting busy with her BF and the tape has been leaked to an online pornsite.
The tape was reportedly shot a few years back and features "innocuous nude shots" of Leighton, 23, with the major exception being an exhibition in masturbatory foot massage on her BF.
A porn site inked the deal to buy the tape and is now featuring pix from the vid on their site.
The actual video is available as pay-per-porn.
Meester’s rep has yet to respond to a ENQUIRER query for comment.
