How old is Sel turning? She's 20 today!

It's July 22nd, so Selena Gomez is officially not a teenager anymore. She'll be spending the day celebrating at the Teen Choice Awards.

She'll be there with Justin and meet up with Demi Lovato. Maybe there'll be a picture of them together!

Things with Justin are much calmer now, and they've been happily vacationing in Japan, Malaysia, and Australia to name a few!
