Lindsay Lohan may have stripped for New York magazine, but that doesn't mean she appears in a video performing a sex act on her ex.

The still photos from a sex tape circulating the Internet were initially thought to feature the "Mean Girls" star, but instead have been shown to feature an unknown girl entirely, reports TMZ.com.

The muckracking gossip site claims that an unidentified girl from Illinois and her boyfriend recorded their bedroom exploits, which he then posted to XTube two months ago. Two other videos showcase the pair, and in these it's more apparent that the girl is not Lohan.

The video surfaced Thursday, and rumors stated that Lohan and her ex-boyfriend Calum Best were the stars. Best is a model and the son of renowned English soccer player George Best.
