Austin Mahone: Shirtless at the Beach!

Austin Mahone goes shirtless as he spends the day at the beach with pals on Saturday (July 7) in Miami, Fla.

The 16-year-old “Say Somethin’” singer was joined by his friend, aspiring dancer Hailey Baldwin, the daughter of actor Stephen Baldwin.

“I had a great day at the beach(:” Austin tweeted that evening. “@haileybaldwin It was fun hanging out with you today(:”

Last month, Austin paid a visit to Z100 in New York City, where he met up with fellow singer Justin Bieber, who also got his big break on YouTube.
