When it comes to the male physique, there are few specimens as near perfect as Chris Brown and Usher. The R&B crooners are super hot to begin with, but their incredibly toned abs and pecs just add to their already sizzling status. While both men bust their (undoubtedly rock hard) booties at the gym, which shirtless pop star gets your vote for the best piece of eye candy?

Chris Brown, 23, is far from shy when it comes to showing off his body. His bare-chested, pretty much flawless figure makes appearances in music videos like 'Strip' and 'Sweet Love,' and he's also been known to shed his shirt during live performances. But the 'Don't Wake Me Up' singer is also generous in the social media front, tweeting pictures of his smokin' hot bod for Team Breezy's viewing pleasure.

Meanwhile, 34-year-old Usher is still giving his younger brethren a run for their money with his rock hard abs. When he's not working or spending time with his kids, the 'Numb' hit maker gets his sweat on at the gym, and he's constantly tweeting photos of himself at the punching bag or in the boxing ring... So, we'd like to take this time to thank Usher's personal trainer for the singer's upper torso. And like Breezy, Ush likes to get half naked in his videos as well, stripping for clips like 'Lemme See.'

Check out some more pictures of Chris Brown and Usher shirtless (yeah, you're welcome) and vote for the hottest  shirtless singer below!
