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.
The 21-year-old actress entered the centre following her arrest for DUI (driving under the influence) after crashing her car on Sunset Boulevard.
Since leaving rehab, Lindsay has been seen out partying wearing the bulky ankle device, which measures the alcohol content in the wearer's sweat and relays the information to a monitoring centre.
The bracelet is worn 24 hours a day and a silent alarm is triggered if it is tampered with.
Last week, Lindsay was spotted enjoying an evening with Cameron Diaz's alleged ex-lover Criss Angel.
The star was seen holding hands with the 39-year-old magician at Las Vegas nightclub Pure before the pair left together at 5am.
Onlookers claimed the pair then went back to Lohan's hotel suite. |
