Austin Mahone is definitely one of Teen’s favorite stars of 2012, and we were lucky enough to catch up with him for entire day! The ‘Say Something’ singer recently had a busy press day in the Big Apple, and filmed the whole thing for us! Not only that, but we got to chat with him on the rooftop of our NYC office where he was a total sweetheart. He sang some festive tunes, did a quick rap, and even talked about meeting Taylor Swift and getting career advice from Justin Bieber. Between two hits singles, 2012 was definitely big for him, but we have a feeling 2013 will only be bigger! Watch Austin’s entire episode of My Day. My Life. above!
