Harry Styles treated fans to a glimpse of his abs as One Direction hit Miami.

The group are currently in the States as their Take Me Home tour visits the US following a successful run around Europe.

A select number of fans in the Florida city got a little more than they bargained for, however, as they met their idols Harry Styles and Niall Horan.

However, it was the former who grabbed the attention, going topless and sporting a small pair of shorts.

He showed some impressively toned bodywork that perhaps gives credence to rumours that the lads have hired fitness gurus to help build their physiques.

One Direction were also seen on a private yacht as they caught a tan in the Florida sun.

The 'Kiss You' group are due to play in Ft. Lauderdale on Thursday (June 13).
