Lilo, 22 has used her private Twitter account to vent her anger towards her now ex-girlfriend - the 31-year-old DJ Samantha Ronson. The pair, who began dating last summer, apparently split up at swanky L.A. hotel Chateau Marmont at the weekend after a huge row over Lilo's partying and flirting with men.

It sounds like the break-up was due to Sam cheating on the actress as well as the DJ's drug abuse - LiLo directed these comments to Sam's Twitter account:

'I was right all along. Cheat.'

'Being cheated on does wonders to you. I’m doing this publicly because u&ur friends call [US magazine] People. So you win, you broke my heart. Now go away. I loved you.'

'stop doing drugs.'.

Oh dear! It looks like Lindsay is well clear of Samantha - what do you think? Comments please!
