Lindsay Lohan reportedly launched a foul-mouth tirade at ex-boyfriend Calum Best after a sex photo appeared on the web.

The lothario son of footballer George Best is said to have sent steamy footage believed to be him and the Mean Girls actress to a friend’s phone.

As a result, the 21-year old called up her former beau with an abusive attack blaming him for the photo leak, claims the Sun.

A source, who overheard the rant, said Lindsay was screaming: “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. It's everywhere now, all over the net, everyone's seen it, how f***ing could you?"
