Lindsay Lohan is not in the sex tape

Lindsay Lohan is not the star of the sex tape photos circulating the internet after all.

Lohan, 21, found herself at the center of a sex scandal Thursday after British newspaper The Sun published grainy images from the internet video, claiming the footage showed Lohan performing oral sex on ex-boyfriend Calum Best, who she dated briefly in 2007.

But, as it turns out, the real star of the show is a random chick from Illinois, who decided to get frisky with her boyfriend and a video camera.

The stills were reportedly taken from an XTube video posted two months ago, and that the guy whose "member" is featured in the photos has actually posted videos before.

Calum -- the son of late soccer legend George Best -- instantly denied the reports, and now website TMZ.com says the other stills taken from the sex tape show the woman in the clip bares few similarities to the Mean Girls star.
