hirtless Harry Styles ALMOST suffers a wardrobe malfunction as he soaks up the sun with One Direction band-mates in Rio

They’re currently in Brazil as they continue to work, or rather sing, their way through the South American leg of their epic Where We Are stadium tour.

But while the One Direction boys have a long way to go before they conclude proceedings with a final show in Miami on October 5, they took advantage of their sunny surrounds on Thursday by letting their hair down – and taking their shirts off – on the grounds of their luxury hotel. 

However, tattooed Harry Styles almost revealed a little more than expected as he relaxed with band-mates Liam Payne and Zayn Malik.

Indeed, the tousle-haired star tugged at his soaked shorts after taking a dip in the pool outside Rio De Janeiro's Fasano Hotel, but appeared to pull a little too hard - giving onlookers a flash of his groin in the process.

Catching the eye as always, Harry showed off his growing collection of inkings, his long hair tied in a messy ponytail as he ventured into the water once more.

The singer also revealed two new additions in the form of matching branches on his hips.

Shirtless Harry was in typically high spirits while he and his two band-mates soaked up the sun ahead of their opening Rio show at the Brazilian capital’s Parque Olimpico.

Zayn, 21, revealed an equally impressive collection of body art as he sauntered close by, his hair hidden beneath a black woollen beanie hat.

The Bradford born star – engaged to Little Mix singer Perrie Edwards – also showed off an increasingly toned upper body, the result of rigorous pre-show workouts.

Elsewhere Liam, 20, wore a red baseball cap and black shorts as he took full advantage of the pool by lounging in the shallow end.
