Calum Best has reportedly called it quits with fairweather girlfriend Lindsay Lohan after complaining the actress is ‘too boring’ when she isn’t dropping X or downing Vodka and Red Bull Energy Drinks.

“Calum called Lindsay on Friday (20Jul07) and said that he was finding her post-rehab existence dull and that he didn’t want to give up partying. “Calum loves Lindsay, but he’s simply not in the same place as her anymore,” a source gushes to the tabs.
