You know how she essentially blamed him for her stint in rehab? Well, he's now saying he's not to blame because Selena has no off switch when it comes to booze. In short, it's your classic case of 'he-said-she-said.'
TMZ report that "Bieber and his friends are laughing at Selena's 'bad influence' claims, because they say she's always the drunk at the party. Bieber acknowledges he gets wasted, but whenever he had parties Selena was downright competitive ... smoking as much weed as the guys and sometimes outdoing them. They say she was also HEAVY into booze. We're told Justin believes Selena's parents are behind the blame game, because they HATE him. He thinks they are fueling Selena's anger and making him a scapegoat. Justin says he's happy he's no longer with Selena because she's just too high maintenance ... and out of control."
Not to mention a pretty expensive date by the sounds of things.
