Bieber and Gomez show a lot of PDA (and skin)!
What a difference a year makes!

Once upon a time, Justin Bieber was just a scrawny little fella, and while he’s not exactly all beefed up like Kellan Lutz or anything nowadays, he’s filling out his frame a bit. The Biebs was showing off his guns in his hometown of Stratford, Ontario on Friday in a black tank top.

Of course, JB has had some help with perfecting his physique (in the form of a personal trainer).

According to Us Weekly, Justin’s trainer, Dolvett Quince, will be joining NBC’s hit weight loss show, The Biggest Loser, as one of the trainers. He’ll join the other new trainer, tennis pro Anna Kournikova.

Justin has been enjoying some down time around his hometown, along with his girlfriend Selena Gomez and they’ve been having all kinds of fun. Check out some photos of them out and about from earlier in the week below!
