One Direction's Niall Horan and Harry Styles enjoy a shirtless day at the pool in Miami, Florida. The two heartbreakers couldn't help but capture the attention of a whole gaggle of girls.

19-year-old Niall was followed by a trail of fans as he made his way poolside to join Harry. The two boys enjoyed some downtime outside of their five-star hotel during their Take Me Home tour in the U.S., playing Chicken and leading a round of water aerobics for friends and fun.

The boys took a few breaks from their games to pose for photographs for some lucky female onlookers who crowded the area. According to The Daily Mail, Niall even took a happy picture with a toddler who was wading in the pool with her mother.

Harry and Niall's day of good clean fun was quite different from what their fellow band mates were caught doing recently. Zayn Malik and Louis Tomlinson were spotted smoking some rolled up cigarettes. According to The Daily Mail, some fans have speculated that Zayn and Louis were smoking marijuana.

In the pool, Harry showed off  his newly toned and bronzed body, and flashed his numerous tattoos.

Ramzy Khachik, who is in charge of the boy's workout regime, recently told The Sun about  Harry's 2 am session, omg! News reports.

"Harry gets him up to train at 2am," Khachik said. "It's quite funny that a heart-throb like Harry isn't out at 2am with a girl."

At least the boys are feeling better. According to omg! News, Niall and Harry had previously complained about feeling tired and ill after their Take Me Home tour in Mexico. Perhaps the relaxation in Miami has helped them feel ready for the next leg of their tour.
