Today is Austin Mahone's 17th birthday. Who is Austin Mahone, you ask? Well, you've heard of Justin Bieber, right? Austin is another huge pop dreamboat coming up through YouTube, just like Justin did. Learn about him and feel very ahead of the pop-culture curve!

OK! News: Justin Bieber Responds to Rumors about Rehab.

1. He's adorable. Duh.

2. He made himself a pop star via YouTube. He began by posting videos of himself covering other artists (including Justin Bieber!) before releasing original music in 2012.

3. His trademark is his trusty baseball cap. What kind of hair is he hiding under there?! He did take it off for a special occasion at the White House…

4. He performed last Sunday at the White House Easter Egg Roll. Trust President Obama to always be on the cutting edge of new music!

5. He will join Taylor Swift on her enormous RED tour starting in May. Fingers crossed for a "You Belong with Austin" duet.
