Leigh-Anne Pinnock looks incredible in tiny black bikini as she strikes a sultry pose in a sand dune

She is one quarter of Little Mix who is known for her incredible frame.

And Leigh-Anne Pinnock sizzled as she modelled her swimwear line in a sultry Instagram snap on Monday.

The songstress, 28, slipped into a tiny black bikini which showcased her incredible frame as she posed on a sand dune in the throwback snap for her In A Seashell brand.

A tiny top revealed her perky cleavage and drew the eye to her taut midriff.

A pair of matching bottoms displayed her lean legs as she posed in the desert wearing a pair of high-tops.

The beauty completed her look with a glamorous palette of make-up and futuristic shades.

Earlier in the day the newly-engaged star posed in a white bikini from her range.

She wore the garment while standing on the side of a boat. 

Leigh-Anne became engaged after her beau of four years Andre Gray popped the question last month.

The Little Mix singer is clearly feeling bridal vibes as she shared a picture of herself in the same bikini on her grid over the weekend.

Captioning the image, she penned: ‘Counting down the days until this is possible again… until then we can bikini prep!’ 

But the view in the foreground, from a previous holiday, was just as good as the star happily displayed her toned midriff and slender pins as she sultrily arched her body for the snap. 

The Woman Like Me hitmaker’s windswept curly tresses cascaded over her shoulders while she highlighted her stunning features with a subtle sweep of make-up.

The singer got engaged to footballer boyfriend Andre, 29, last month on their fourth anniversary and her bandmates think she will be tying the knot ‘soon’ because she ‘has no patience’. 

Jesy, 28, and Jade Thirlwall, 27, joked Leigh-Anne has been ‘waiting years’ for Andre to pop the question as they praised the sportsman for his ‘beautiful proposal’ during an interview on Heart Breakfast recently.  

Jade said: ‘Honestly, when I tell you that girl’s been waiting for years! Honestly. 

‘Every time Andre does anything romantic, she messages us, she’s like ”it could be now”, we’re like ”Leigh…chill babe”.’ 

The Geordie beauty admitted all the group members, including Perrie Edwards, were overwhelmed with emotion at the idyllic home proposal.

Jade added: ‘Yeah it was so lovely, he did so well, it was a beautiful proposal we were so emotional weren’t we Jess?’

‘Well we didn’t know when it was going to happen but we knew it was going to happen at some point.’

On their upcoming wedding, Essex beauty Jesy said that while the pair ‘can’t give anything away’, they’re sure the ‘extravagant’ ceremony will take place soon. 

The songstress explained: ‘Well obviously we can’t give anything away, but we know it will probably be soon because Leigh-Anne has no patience and she will just want to hurry up and do it.

During an appearance on her bandmate’s new MTV show Served! With Jade, Leigh-Anne revealed how Andre pulled out all the stops for the big moment, setting up an outdoor cinema and playing her a romantic personalised film.

Leigh-Anne said: ‘[Andre] basically set up this outdoor cinema, so there was a walkway of fairy lights and candles and I was like, “this is a bit much for an anniversary, what’s going on here?”   

‘So we started watching a film, and then halfway through it cut out and our song started playing, and then there were videos and pictures of us and there was this book on the screen that said, “four years and forever counting”, and it kept opening up with pictures of us and stuff.’

‘And then it just said, “Will you marry me?” and he was on one knee,’ Leigh-Anne continued, as she admitted that recounting the moment was making her emotional.
