Lindsay Lohan has reportedly been dumped by on/off lover Calum Best - because he doesn't like her being sober.
The model, the son of late soccer legend George Best, is not ready to cut down on his partying and thinks he is no longer suited to the 'Mean Girls' actress, who is teetotal after completing a rehab programme for alcoholism.
A source told Britain's Daily Star newspaper: "Calum called Lindsay last week and said he was finding her post-rehab existence dull and that he didn't want to give up partying.
"He loves Lindsay but he's simply not in the same place anymore."
Lindsay - who began dating Calum earlier this year - has been wearing a special ankle bracelet to monitor her alcohol consumption since officially finishing a 45-day stint at Malibu's Promises rehab clinic on July 13.
