Austin Mahone: I Can Undo a Bra with Breast of Them

Austin Mahone was all braggadocio at LAX Tuesday, telling our photog he's the champ when it comes to unstrapping his conquests. 

Austin's only 19, but he gives himself a 10 and explains his tried-and-true techniques.

The singer then takes us south to his feet, and reveals how much he dropped for a pair of "Back to the Future" kicks.
