Gigi Hadid shows off her stunning figure as she strips to a bikini for latest Tommy Hilfiger campaign

GIGI Hadid had the effortlessly sexy look down to a tee as she stripped to a bikini and flashed her bum in her latest modelling campaign for designer Tommy Hilfiger.

The catwalk beauty - who is rumoured to be recently engaged to boyfriend Zayn Malik - perched her hand on her hip and threw a denim jacket around her shoulders as she posed in yellow print swimwear.

Her bling ring - which dazzled from her wedding ring finger last week - was nowhere to be seen as she got into work mode.

The clingy swim top boosted her cleavage with its low cut design while the striped waistband perfectly flattered her rock hard tummy.

She struck a sexy grin as she cocked one hip higher than the other to show off her lean legs.

Meanwhile, perhaps hinting at her besotted mood, she threw a delicate gold chain around her body which featured a gold heart pendant with the word 'love'.

She kept the accessory around her super-toned abs as she struck a pouty side-pose after switching to red and white swimwear in the same design.

Gigi, 21, again packed on the attitude as she stared straight into the camera lens and cheekily flashed her bum in the high-hemmed bikini pants.

Wearing minimal make-up and with her hair in natural waves, the catwalk pro's natural beauty shone through in the series of shots for the American brand.

Another saw her switch to an all-in-one black costume emblazoned with the phrase 'Young America' as she got sassy in a denim shirt cover-up, baseball cap and bright white trainers.

Bella Hadid's older sister maintained the sassy streetwise theme in her final image which saw her work the camera in a pair of patch jeans and a red crop top.

The denim trousers featured the same design as her personalised bomber jacket while this time, the logo on her shirt read 'Better Together'.

Her smiley photoshoot for the high-profile label comes days after the Victoria's Secret Angel sparked rumours she was engaged to her popstar boyfriend Zayn.

She wore a never-before-seen band on her engagement finger and did nothing to hide the sparkler as she went for a walk in New York.

The following day, she was spotted leaving her apartment in the Big Apple, wearing the thin band which sparked engagement rumours earlier this week.

Dressed in a 70s-style outfit consisting of cropped ankle skinny jeans, striped fur coat and pink lens sunglasses, the 21-year-old model kept her left hand across her body as she held onto the strap of her handbag, giving onlookers plenty of chance to see the ring on her hand.

She had done nothing to hide the slim sparkler on her wedding finger either as she headed out into the city.

Meanwhile Pillowtalk singer has steadily been adding ink to his body over the years and on Tuesday night, the 24-year-old showed off his latest addition - a very romantic tattoo.

Heading out in New York, Zayn’s right hand clearly had the word ‘Love’ in joined up writing across his knuckles.

The pictures of Gigi and her new ring come just weeks after it was claimed she had turned down her One Direction star boyfriend after he popped the question.

A source close to the couple told Gigi wasn’t ready for marriage, saying: “She’s only 21 and doesn’t feel ready to tie the knot, so she turned him down.

“She’s seen her mom [Yolanda Foster] go through two messy divorces, so Gigi wants to make 100 per cent sure Zayn’s the one before she makes a lifetime commitment.”
