Happy Birthday, Justin Bieber! The pop star sensation, who also used to complement his income by being an underwear model (even before Shawn Mendes) is turning 25 today. What a wonderful opportunity to look back at some of his hottest moments, and conduct a close inspection of those famous abs.
Unfortunately, in recent months Bieber wasn’t very generous with shirtless photos on his Instagram page. Plus, his abs are not covered all over in tattoos… Thankfully, however, we still have a lot of beautiful shots from the past.
