Introducing Buff Bieber

From the looks of it, Justin Bieber’s personal trainer certainly has earned himself his Christmas bonus, huh.

I mean, he certainly is turning that skinny white boy into one buff young man.

And Beliebe you me, the “Heartbreaker” singer is just loving showing off his progress. By which I mean his hard pecs and six-pack.

Good for her him.

I wonder what his tushy’s looking like these days.

Urgh, alright already: I shall take myself to the gym now.
