Gigi Hadid puts her incredible bikini body on show again in Miami... and manages a brave face too after death of her beloved dog

In-demand model Gigi Hadid spent her 20th birthday 'with her toes in the sand' in Miami, Florida.

However, it wasn't all fun and games for the star, who spent her time flaunting her stunning figure in a series of swimsuits for Seafolly.

She continued the sexy shoot on Friday, but was then burdened with the news that her childhood pet - dog Lucky - had passed away while she was on the job.

The busy model made time to share some love for her beloved dog on Instagram, posting a sweet throwback snap and writing: 'Rest in peace my angel boy.'

First Gigi showed off her toned figure in a black tankini, with white piping and embellished with a colorful feather pattern.

Her long blonde locks were slicked back for the shoot, and harm arms were loaded up with a collection of gold jewelry. 

The daughter of The Real Housewives of Beverly Hills star Yolanda Foster also sported a pair of olive green Nike sneakers, as she was spotted making her way toward the beach in Miami.

The first series of shots of the burgeoning model showed her posing outside of the beach in the grass, alongside palm trees. 

She later accessorized with a large, dramatic pair of dangling gold earrings, and was seen sporting a high ponytail. 

The blonde beauty was seen covering up in a colorful, patterned blanket as she took a break on set, while someone on crew shielded her from the sun with a large, black umbrella.

She was assisted by her glam squad, who were seen attending to the girlfriend of singer Cody Simpson's hair and makeup.

Gigi then made a quick change into a more traditional-style bikini, which bore a striped pattern and was black and bright pink.

The colorful bikini was also embellished on the stylish bottoms with 'SF,' the Australian company's initials.

This time she swapped out the majority of her gold accessories for a few statement pieces, featuring large pearls.

Her long blonde locks were taken down from the high ponytail and sported in her natural, loose waves.

Modeling this new bikini, Gigi posed in the sand, showing off her athletic figure as she hung onto a pair of the beach's traveling rings. 

She was spotted exploring other attractions at the beach's gym, and shared a smile in one photo as a man practiced acrobatics on a bar nearby.

Following the pink bikini Gigi donned a tiny red and white striped bikini, which boasted a small beach umbrella pattern. 

She went barefoot for the shots, as she she modeled poolside, accessorizing with a new collection of colorful beaded bracelets.

Following a few sandy photos by a private cabana, Gigi was seen cooling off as she put her stylish suit to use, stepping into a nearby pool.

At one point she even donned a white baseball cap as she sported the striped suit, with the brand's name - Seafolly - printed on it in bright pink in all capital letters.

She then switched into a fourth suit, a black and white marbled bikini, which featured a cut-out on the front and along the sides.

For this look Gigi headed into the ocean, braving the waves as she showed off the bikini's stylish design.

She was quite active in this look, as she the star was seen running through the waves and along the sunny beach as well.

Gigi was then joined by a group of five smiling children in colorful, patterned swimsuits, with whom she was seen chatting for a bit.

She then grabbed hands with the young models and they were photographed as they happily sprinted through the waves.

Gigi then chatted with photographers as she tried on yet another bikini to shoot a few pictures in the sand. 

 However, she returned to shoot by the water after that, trying on another stylish tankini - this time decorated in blue, with black trim.

She stood by the water's edge as she sported a large pair of gold headphones, which coordinated with her stylish gold accessories.

Her blonde locks - now a bit damp from the water - were styled in a center part and slicked back and out of her face.

The brave star then ventured into the waves as she held onto her technology, wearing her headphones around her neck.  

The day before - on her 20th birthday - Gigi took to Instagram to share a sweet throwback photo alongside her dog Lucky, who had passed away.

She had been posting about him earlier, calling for his swift recovery as he had taken ill, but then shortly returned to Instagram to share her goodbye.

'On my 9th birthday an angel came into my life... And on my 20th birthday, that same angel went to a place where he can watch over me a lot better..[heart emoji]'

She continued, alongside a photo from her as a child with her dog as well as a recent snap of the two: 'To an irreplaceable companion, Rest In Peace my angel boy.'

She also retweeted sentiments from sister Bella Hadid: 'rip to our sweet lucky...you'll have a beautiful time in puppy heaven...i love you forever' and brother Anwar Hadid: 'rest easy lil brotha...'

Gigi was already in Miami at the time, lounging by the pool as she kicked off her photo shoot for Seafolly. 

She was seen posing in three bikinis and two one-pieces on Thursday, while showing off her gorgeous figure.

Perhaps her best look for the day was a retro red bikini with white polka dots and high-waisted bottoms, and the birthday girl looked like she was having fun as she pulled poses in the two-piece.

Gigi’s other bikini was a denim patchwork triangle number which left her flat stomach on show, but at one point she wrapped a blue and white tie dye sarong around her.

The model looked smoking hot as she took several photos leaning against a blue convertible in the two-piece, with an unbuttoned denim shirt over the top.

The one-piece swimsuits were decidedly more daring, and the first one the star modelled was a futuristic coral creation with mesh sleeves and matching panels on the sides.

Get the gladiator look with these Chloé lace up sandals

She's becoming one of the most sought after fashion models, and on day 2 of her photo shoot for Seafolly, Gigi Hadid showed them why. The blonde beauty posed in a number of skimpy bikinis that flattered her amazing figure, but her footwear was as noticeable as her swimwear.

The 5'10" stunner teamed her patchwork two piece and chambray shirt with a pair of suede Chloé sandals that ticked so many boxes on the trend scale. Lace up? Check! Gladiator? Check! Wedge heel? Check!

This silhouette will be everywhere this season with designers like Givenchy and Rodarte tapping into the look so it's best to get them now. The Sienna shoe is available in black and beige at Net-A-Porter (right).

Paired with funky blue reflective sunglasses, it was a difficult look to pull off, but Gigi naturally managed it with ease.

She then slipped into a black one-piece with a racy plunging neckline and cut-out sections across the back, along with tan sandals, and was later seen enjoying a quick break on a sunlounger while dressed in white. 

Fortunately for Gigi, she didn’t have to wait too long in between looks as she kept the same hair and make-up throughout the shoot.

The blonde wore her long locks in sexy beach-ready waves and kept her make-up natural to highlight her glowing complexion.

Gigi had her trusty monogrammed mobile phone to hand throughout her special day as she stayed in touch with family and friends. 

Taylor Swift was among those to share their well wishes on Twitter, writing: ‘It's both @GiGiHadid AND @Jaime_King's birthday today-- I adore these girls and I'm so happy they were born. #SQUAD.’ 

Gigi replied: ‘Love you @taylorswift13 T + April babies = [heart symbol] cc: @Jaime_King.’

She wrote: ‘Birthday-wishin that my lil man pulls through and recovers... wish I could be there to remind him how much I love him!! #prayforlucky .’

Gigi travelled to Miami from New York, and tweeted on Wednesday before she set off: ‘Headed to Miami with the @seafolly team. Get to spend my birthday tomorrow with my toes in the sand!’
