Bikini girl Selena Gomez enjoys poolside fun in Miami with Justin Bieber

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.

Selena Gomez quizzed over "brother" Bieber

Selena Gomez has laughed off a past comment she made describing Justin Bieber as a "little brother".

The Wizards of Waverly Place actress was quizzed about rumours suggesting she is romancing Bieber during an appearance on The Ellen DeGeneres Show on Tuesday.

DeGeneres opened the questioning by playing a clip of Gomez's past appearance on the show, during which she brushed off speculation of a romance, comparing the 'Baby' singer to a family member. "What do you have to say now?" she asked Gomez.

"Don't take me to jail!" responded the actress. "I don't know! I don't know!"

As the 18-year-old dissolved into giggles, the host went on to suggest that Gomez and Bieber had been trying to hide their romance until going public at the Vanity Fair Oscars party in February, joking that Gomez had made a "fool" of her.

"I really didn't!" said Gomez. "I promise you I didn't! He's just sweet!... I didn't lie to you, though. I will say that!"

The star didn't directly comment on her current relationship status with Bieber, who is on tour in the UK, but did agree with DeGeneres when the host suggested that a little brother isn't someone you would want to date.

"Well, no," she said. "That would be weird and wrong."

Gomez is currently promoting her new single 'Who Says?' and has said that she will launch her first headline tour this summer.

Selena Gomez 'dreams' of Spanish album

Selena Gomez has revealed that she hopes to release a Spanish-language album in the future.

The singer and actress, whose father is Mexican American, said that it would a "dream" to record an LP of Spanish tracks.

“I have Shakira’s [bilingual] album and exactly what she did is my dream. I feel like for my family it would make them really proud," she told Lopez Tonight.

"But because I have so many other things... I have to perfect it. I want my dad to come out and make sure I’m doing it right. So I want to take time with it, but it’s my dream to put out an entire album in Spanish."

Gomez, who has been romantically linked to Justin Bieber, also discussed the meaning behind a recent photo of them together at a high school football game.

She explained: "I’m trying to convince Justin to eat my food, because he wouldn’t eat anything and I was eating nachos and a corn dog and I was like, ‘Why is no-one eating?’"

Earlier this year Gomez revealed that she was learning to speak Spanish, admitting: "I can understand it better than I can speak."
