WWW- Lindsay Lohan’s ex boyfriend Calum Best denies that images making the rounds are from a sex tape of them.

“Sorry to disappoint you, but it’s not Calum in the tape,” his rep tells Usmagazine.com.

Grainy photographs of a young woman vaguely resembling Lohan were posted online this week leading to reports that Best had leaked a sex tape.

Lohan and Best, a British model, dated in 2007.
