That's right, according to a source, Joan may be more on the mend than we might think:
Justin Bieber's definitely been workin’ out those arm muscles…and he’s not shy about showing them off!
Our little Bieby recently proved once again that he's all grown up, as he pulled out ALL the stops at the Capital FM Summertime Ball this past Saturday in London!!
Check out the Biebs performing Die In Your Arms from his upcoming Believe album (above)!!
We LOVE this track!
Justin also performed some of his older hits like Baby (in a MUCH deeper voice) and Somebody To Love, as well as more Believe songs like Boyfriend and All Around The World!
Somebody To Love:
