Austin Mahone f/ Flo Rida - Say You're Just a Friend

Austin Mahone seems to be expanding his contact list (or Facebook friends, whatever method you prefer) at a rapid pace. First, he announces that he's opening for -- ahem --Taylor Swift, and now his brand-new single, "Say You're Just A Friend," features Flo Rida. Not too shabby for a 16-year-old.
