Ch-ch-check out Obama's AH-Mazing final WHCD speech (above)!
The singing bad boy is totally dismissing reports that he is to blame for her habit for booze, prescription pills, and weed.
JB and his pals are actually L-O-Ling over claims that he's a "bad influence" because he vows that the pop princess is always sloppy, drunk, and stoned at parties. And when she isn't, she gets competitive trying to out-smoke and out-drink the boyz!
So Bieby is going to just pretend it's one BIG coincidence that he was just busted for pills and weed. LOLz!
Still, Selena is a smart babe and has the power of free will. We doubt Justin forced those pills down her pretty throat.
The major difference between Selena and Justin is that at least our gurl is willing to change for the sake of her health…
…even if she did quit treatment early!
