Lindsay Lohan lit into ex-boyfriend Calum Best after a sex tape, which supposedly features the British lothario and the former Mean Girl in a naughty tryst, found its way to the web.

Tabloid tattles claim Lindsay has made a series of screeching phone calls to Calum following last week’s release of that blurry clip supposedly captured, and later hacked, from Calum’s phone last summer.

Lindsay was screaming: “I can’t believe you would ever fucking do this to me, I should have listened to everyone….I should never have fucking trusted you.”

In a later voicemail, the Razzie winner told Calum: “It’s everywhere now, all over the net, everyone’s seen it, how fucking could you?”
