Well its fairly normal for 14 year old boys to not have abs yet.
zac defilently has them now lol
and far better than bieber's
lol bieber doesn't even have any

yeah. and it's really sad to see bieber shirtless. girls nowadays like bieber doesn't wear a shirt anymore tsk tsk tsk lol jk
It's not exciting to see Bieber shirtless. Unless you have Zac Efron or Taylor Lautner abs, you should not be shirtless.
there should be like a rule where zac is illegal to wear a shirt

^^

haha
lol i just that from a tweet back then
