Lindsay Lohan has slammed her former flame Calum Best for posting a sex video of them in the internet. The actress got furious with Best after knowing he allegedly leaked a tape onto the web that he had filmed when the two of them were dating last year. “I can't believe you would ever f***ing do this to me, I should have listened to everyone," the Sun quoted a source that overheard the star screaming. "I should never have f***ing trusted you," Lindsay added. However, it is said the video is fake and Calum’s rep has denied the reports, claiming, “It’s not Calum. If it was Calum we would have it shrink-wrapped and put out onto DVD for Christmas.”
