Rumor mill, you've hurt us so many times before that we beginning to find it hard to muster up enthusiasm for your tall tales. Megan Fox naked in Jennifer's Body? Lies. Sandra Bullock full frontal in The Proposal? Lies. Hayden Panettiere nude in I Love You Beth Cooper? Lies, dirty lies.

But still, a tiny part of us can't help but hold out a bit of hope for the latest story about a purported Lindsay Lohan sex tape. It's a rumor we've heard before, but this time, just maybe, it's the real deal?

Showbiz Spy reports:

An unnamed waiter has reportedly tried to sell a sex tape featuring Lindsay Lohan.

According to The Mirror, a 47-second clip of the actress was rejected by Hustler due to copyright concerns, with the video's owner instead advised to release the footage to an "offshore porn site".

A source said: "This video file is dynamite. It is pretty seedy and shows Lindsay engaged in a particular sex act which, obviously, should remain behind closed doors. Lindsay was desperate to start 2010 off on a good footing and this is the very last thing she needs. If and when it is released on the internet, via a spurious, unofficial website, there is absolutely nothing she or her lawyers can do about it."

Let's all guess what this "particular sex act" that "obviously should remain behind closed doors" might be.
