Gigi Hadid celebrates her 20th birthday with a poolside photo shoot as she shows off her model figure in a series of sexy swimsuits

Most 20-year-olds spend their birthdays celebrating, but Gigi Hadid was hard at work instead on Thursday.

However it wasn’t such a tough day at the office for the model of the moment, who lounged by the pool in Miami, Florida while clad in sexy swimwear.

Gigi was modelling for a Seafolly campaign, and posed in three bikinis and two one-pieces 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.

Suit up in style

For some of us, diving into the impending doom of swimsuit season has got us all in a panic but everything seems peachy with Gigi as she models for an upcoming Seafolly campaign in this exquisite crew-necked, coral colored bathing suit.

The mesh paneling of this one piece turns up the heat to what would have been a conservative design if it weren't for the stroke of genius that accentuates her trim waist. Cut-outs, high-waisted bottoms, bralette tops and and strappy bikinis are on trend for this summer, making the entire collection from Seafolly totally wearable.

You can outfit this little mesh number with heavy gold accent jewelry, or throw on some jean shorts over it to wear as a top. Regardless, you'll be sure to make someone's head swim this summer.

The 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. 

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.
