Twice as nice! Bella Hadid flashes a hint of under-boob as she steps out in two outfits in Miami on girls' trip with Kendall Jenner and Hailey Baldwin.

She was just in the Bahamas for a sun-drenched celebration of Hailey Baldwin's 21st birthday milestone.

And the fun continues on Monday in Miami as Bella Hadid traded in the bikini for two more head-turning outfits as she set off the Florida coast.

The 21-year-old left little to the imagination in her tiny white crop that flashed some under-boob and her svelte torso as she stepped out alongside BFFs Kendall Jenner and Hailey's birthday girl.

She smiled from ear to ear as she led the way for her pals, rocking a pair of very ripped jeans and flowing white shirt.

Bella's impossibly toned torso was put on full display as she headed out of her car, also sporting a comfortable pair of white sneakers.

The catwalk queen had her brunette tresses scraped back into a bun, showing off her perfectly made-up complexion.

Just before stepping inside the awaiting luxury yacht, Hailey changed her look into something more comfortable.

The star ditched her crop top and jeans for a beige mini dress that highlighted her gym-honed physique.

Bella looked in high spirits as she stepped out onto the dock before joining her pals on the boat.

Meanwhile, Hailey flashed some leg in a frilly floral print and pink mini dress with a plunging neckline.

The model, who is the daughter of Stephen Baldwin, stepped out in beige sneakers and accessorized with layers of gold necklaces and large hoop earrings.

Hailey looked to be driving the boat as a group of pals mingled in the back.

Kendall, meanwhile, kept it casual and comfortable in a black T-shirt and leggings as she chatted away on her phone ahead of a photo shoot.

The ladies all looked relaxed, especially after spending a sun-soaked getaway to the Bahamas as part of Hailey's 21st birthday.

From relaxing on the beach to the crystal clear waters, the girls had plenty of fun in the sun these last few days.

The chance to catch some rays was a great one for Bella, who last week walked in the Victoria's Secret Fashion Show in Shanghai, China.

She reportedly received a 'gorgeous, huge bouquet of flowers along with a super sweet note,' from her 'ex' The Weeknd during the show, according to Hollywood Life , just days after he was seen sneaking out of her New York apartment .

Bella and the singer - real name Abel Tesfaye - dated from early 2015 until November 2016.

When they split, he hooked up with Selena Gomez, dating for 10 months.

Selena and her ex Justin Bieber have now since rekindled their romance, which may have inspired The Weeknd and Bella to do the same.

A report claimed this week that Bella had been in a relationship with another Canadian, a Drake musician, 31, until he 'ghosted' her.

The pair are said to be 'no longer talking' after he ended their fling via text message a month after they got together.

The couple started dating in October - almost a year after the Victoria's Secret model split from The Weeknd - but things are now believed to have turned sour, according to US Weekly .

'Things ended up text when he basically ghosted her,' a source told the publication. 'They are no longer talking.'
