Last night the socialite put on a brave face and headed out for a party in Beverly Hills (we only imagine the looks fellow guests gave her).

Earlier this week it was revealed that a short clip of Lindsay “performing a sex act” on a waiter was being sold to an off-shore porn site. But of course it goes without saying that in the wake of these claims the Mean Girls actress has been quick to deny the existence of any kind of naughty tape.

“I haven't even heard of this," Lindsay said dismissively, before going on to say “there is simply no tape at all”.

Yup, we believe you Lindsay. We believe you…
