In what could be a plot line straight from Gossip Girl, a website has put up images from a sex tape they are claiming features Leighton Meester, the show's star. The site shows grainy images of a young woman's breasts with the words: "This is 100% the REAL Leighton Meester" and "Did you know, she's a natural blonde." The site, Celebhotline.com, requires payment to see the tape. (It reportedly involves the woman's feet in a "sex act.") TMZ claims the tape was shot by an ex-boyfriend several years ago. The 23-year-old actress recently crossed over into music, releasing a pop single called "Good Girls Go Bad."
