Lohan's spitting fire over last week's 'mobile sex scandal' with Calum Best, in which he allegedly filmed a 'sexy moment' between the pair on his phone before texting the flick on to mates. In fact she's so cross there might even be steam coming out of the Mean Girl's ears.

A kindly 'source' earwigged a series of voicemail messages from Lohan to Besty, before buzzing The Sun showbiz desk with all the juicy info.

“I can't believe you would ever f***ing do this to me, I should have listened to everyone. I should never have f***ing trusted you" roared Lindsay. "It's everywhere now, all over the net, everyone's seen it, how f***ing could you?"

How could he? Well. For a man who plies his trade getting shedded and bedding famous women - pretty easily.....

Check out Besty on the prowl after a skinful at the World Music Awards (where he and Lohan first got it on). The interviewer gets a veeery lucky escape ....
