Selena Gomez took a break from her tour schedule for an afternoon of poolside fun in Miami.

The Disney star, who turned 19 earlier this month, slipped into pretty pink bikini to cool off from the Florida heat on Friday.

At one point, she untied her bikini top to avoid getting tan lines as she reclined on a sun lounger after taking a dip in the pool at a luxury Orlando hotel.

The performer, who kicked off her summer tour on July 24 in Costa Mesa, is travelling throughout the US on her Dream Out Loud tour for the rest of this month.

Her boyfriend Justin Bieber joined her for part of the tour last week and was spotted taking in some sunshine the following day in Miami.

Hinting he has been in a rather romantic mood of late, he wrote on Twitter that same day: 'What makes you so beautiful is that you don't know how beautiful you are... to me.'

He also had a great deal of affection for the city too, adding: 'I LOVE MIAMI.'

The 17-year-old was spending time with singer Sean Kingston, who recently recovered from a jetski accident.

Bieber describes the star as a 'real friend.'

He is taking a month off to relax with his pals - and of course Selena - before beginning work on his next album.

Gomez is set to perform in Atlanta tomorrow night.
