And of course, we’re not going to show those photos here, because this is a PG-13 site.

Spotted … “Gossip Girl” star Leighton Meester having sex with her BF… on video.

We’ve learned a Meester tape is being shopped around town. It was shot a few years back, and shows Leighton in mostly innocuous though nude scenes — with several big exceptions … one involving her very talented feet.

We’re told a company called celebhotline.com is negotiating for the video. The company’s spokesperson, Kevin Blatt told us, “We’ve seen the tape and we’re hoping to close the deal.”
