Now we KNOW he’s reformed. We remember a few years back when Colin Farrell, 36, would stay at the Chateau Marmont and walk to all the bars on Sunset for some heavy duty partying. The sexy Irish actor ended up with quite an assortment of short but spectacular flings with various women – including Britney Spears! In those days he was a BIG drinker and not that difficult to pick up, if you know what we mean. Of course, he had a few other bad habits too. Now he says he’s given up whiskey and cocaine and he’s taken up yoga. And he really enjoys it! As we said, now we KNOW he’s reformed.
