Lindsay Lohan rumoured sex tapeCalum Best has denied he co-stars in the currently rumoured Lindsay Lohan sex tape.

The video is supposed to have been filmed by Calum on his mobile phone during his brief fling with the actress last year but after photos began circulating, claiming to show Lindsay performing oral sex on him, his spokesperson told OK magazine: “Calum knows nothing about a sex tape. It is not him in the picture.”

Lindsay’s spokespeople have so far refused to comment on the rumours - possibly because the I Know Who Killed Me actress can’t be sure it didn’t happen during her hard partying era.

A source close to the actress claims Lindsay is “freaking out” over the rumours “because she can’t remember it being filmed”. Another source quoted in the New York Post claims Lindsay is denying it “but privately, nobody believes her.”

The pair first met when Lindsay presented the World Music Awards in London in November 2006 then hooked up again in Los Angeles earlier last year between Lindsay’s various stays in rehab.
