For starters, there's the close-up, look-into-the-camera selfie taken outside in the sun. Justin's a pro at this.
Austin has one too. He just posted this one a few days ago with the caption "Good morning beautiful." Wonder where he got that from...
Let's not forget the performance pic, preferably where he's making a sexy pose and thus causing tweens to scream/hyperventilate.
Or how about the shirtless mirror selfie? No hot guy Instagram page is complete without it, right?!
Here's an Insta pic of Justin Bieber and a friend posing on an expensive bike. Just another day in the life for the Biebs.
Austin's got that one down pat, too. But why aren't either of these guys wearing seatbelts?!
Justin posted this pic with Selena Gomez shortly after they broke up, and the fans didn't know what to think.
And they also didn't know what to think when Austin posted this one of he and Selena at the 2013 MTV VMAs. She belongs with Biebs!
And of course Austin had to post his own version of the hospital pic when he was there a few weeks ago. Feel better, dude!
And Austin even goes so far as to post his in-bed selfie first thing in the morning. Ladies, cue the swooning.
Bonus points for Austin's though, who has a cute kid and no shirt on in his Insta. He knows what he's doing.
