One Direction's Harry Styles & Niall Horan Pose Shirtless—See the Photos

Separate pictures of the singers rocking a bare top surfaced on Twitter

Hey, Justin Bieber, you have a little competition. 

One Direction cuties Harry Styles and Niall Horan have joined in on the whole young-heartthrobs-go-shirtless movement after a couple snapshots of the singers showing off their muscles surfaced on Twitter. 

Horan, who is beefier than we expected, strutted his pecs for his admirers while only wearing a pair of blue sweat pants

Meanwhile, Styles, who showed off his multiple tats, was caught making love to the camera when he showed off his sexy pout and made sure to point at you, yes you, to make it personal (and its working, isn't it?). Unfortunately, we can't tell if he's wearing his sparkly thong. 

When they're not ditching their tops and posing for fans, the two singers are enjoying the single life. 

Niall and Harry recently partied at a new VIP bar called Dandelion after the band's show in Dublin. The duo each posed for photos with fans at the club, and (at least) one lucky lady snagged herself a kiss on the cheek from Styles. 

Should they decide to engage in a shirtless dance party next time they're out, we wouldn't mind seeing pictures of that, too.

Just sayin'.
