Justin Bieber and One Direction member Zayn Malik are both super hot -- there's really no question there -- but which one of these teen heartthrobs had you the most hot and bothered in recent days? Both of the singers posted shirtless pics of themselves via Twitter, and we want to know which of their pics you liked best.

Now, Justin Bieber wasn't really fishing for compliments when he posted this cute picture on his Twitter account. The Biebs actually got a new tattoo of a crown, writing, "new tattoo its a crown if you couldn’t tell." We could definitely tell, Justin, and we love this new piece of body artwork! It's our fav piece of ink he has gotten thus far! To add to the effect, the Biebs made a funny grimace like he would on the tattoo table, even though we bet his shoulder/chest area was still sore the time this pic was snapped.

On the other hand, Zayn Malik seemed to be looking for some praise from his beloved Directioners by posting this oh-so dreamy picture of himself lying shirtless in bed. Malik posted the pic for advice really, writing, "Profile pik?" along with the photo. He looks contemplative, and even though he was probably looking for some comments about how beautiful he is, we really can't blame him, because he is incredibly hot. We'd be pretty much stuck to the mirror 24/7 if we looked like that boy!

So, did you like Justin Bieber's funny shirtless pic better or did Zayn's shirtless pic have you working up a sweat? Vote below!
