Happy Birthday, Justin Bieber! The pop star sensation, who also complements his income by being an underwear model, is turning 24 today. What a wonderful opportunity to look back at some of his hottest moments, and conduct a close inspection of those famous abs.
Thankfully, Bieber returned to Instagram last year – so we’re getting a fresh supply of shirtless photos. But for now, let’s look at the glory of Bieber’s past.
1. This one was actually a gift from his father
2. With all the tattoos
3. “Wowzers”
4. Will taking his shirt off make you follow him on Snapchat?
5. No longer a boy!
6. Nice view
7. Those world-famous undies!
 8. Different undies! (But they’re wet again)
9. Holding on
10. Still sexy when brooding
11. The sun and the Bieber
12. Beach Boy
