It was recently reported that she quit Geordie Shore after five years.

Currently focusing on her new venture, Marnie Simpson braved the chilly temperatures as she slipped into a sizzling lace bikini as she celebrated the launch of Ex On The Beach alongside her co-stars Sofia Filipe and Charlotte Hughes.

The 26-year-old reality star wasn't shy in flaunting her sensational figure in her choice of racy swimwear which drew attention to her ample cleavage as she was joined by her beau Casey Johnson at the event on Wednesday.

Her black lace top offset her thong silhouette bikini bottoms which accentuated her pert posterior and slender pins as she smoldered for the camera at the launch.

Marnie offset her skin-flashing look with a sheer black floor-length kaftan which skimmed her svelte frame with aplomb.

The racy garment's plunging look showcased her lacey bikini top while showcasing her narrow midriff with it's waist belt detail.

Posing in a pair of flat sliders, she worked her raven-coloured locks into a straight style which complemented her natural make-up look.

Series Eight of the MTV show is set to feature yet more boozing, brawling and bonding with eight genetically blessed stars living in a lavish villa in Spain, waiting for the Tablet Of Terror to throw them a curveball. 

Marnie is joined in the villa by Sofia Filipe, a 21-year-old dancer who describes herself as 'one of the lads', and model Katie Champ, 24, who recently came out of a serious nine-year relationship that saw her 'lose her mind'. 

Rounding up the girls is Charlotte Hughes, 24, an Essex PA who describes herself as an 'absolute handful' and her love life as being a ‘complete mess’.

Appearing at the launch, Sofia was sure to turn heads as she slipped into a bandage-inspired bikini, despite the cool Spring weather.

Cosy: Her beau Casey Johnson, who also stars in the upcoming series, was at the photocall

She continued her glamorous look with a dark smokey eye and styled her brunette locks in a soft curl.

While co-star Charlotte continued the swimwear display at the launch in her perilously lowcut white one-piece.

The statuesque beauty's swimsuit boasted gold detailing in the midst of her bust and across her thigh which exhibited her toned pins.

Also in attendance at the event was Casey Johnson, Zach Tull, Tom Litten, and Marcel Stevens. 

Leading the group of boys looking for romance in the villa, is 25-year-old Tom Litten, a pig and cattle farmer from Somerset who boasts a 'shocking' relationship history.

Meanwhile, personal trainer Zach Tull, 23, describes himself as 'heartless', and admits he doesn't want to know what his exes have to say about him.

Marcel Stevens, a football coach, 25, claims he’s 'cool, calm and collected', so should be able to keep calm in the villa, whilst student Sam Lonsdale, 20, will be hoping to get the party started as he claims his biggest strength is being a 'top vodka shotter'.

The original eight won't be alone for long, however, as the Tablet Of Terror will be on hand to bring in some of their most feared and confrontational exes.

One ex who is set to make a splash will be Marnie's current boyfriend Casey Johnson, as the pair were on a relationship break when they appeared on the show.

Whilst it's clear the pair will eventually have a happy ending, given their solid relationship status in the outside world, it is not yet known what drama the pair will get into inside the villa.

What is known is that Marnie does enjoy a dalliance with someone in the villa, in a teaser clip, she said of the 'sexiest moment' of the series: 'It’s obviously when I take a certain someone to the penthouse and give him the best night of his life.'

Marnie and Casey met while filming Single AF, flaunting show rules by getting together instead of dating the contestants as the show required.

However, they split in June last year when Marnie accused him of getting close to another woman.  

Her appearance on the reality hit comes after it was reported that she quit MTV's Geordie Shore after five years. 

The reality star, who shot to fame on the raucous reality series in 2013, will be completing her run on the current sixteenth series of the show and then will 'move on', according to The Sun.

This comes hot on the heels of the brunette sharing her controversial thoughts on the show's authenticity in a now-deleted tweet on Wednesday, branding the series 'fake and scripted'.

Marnie has been known for her fun-loving and wild ways on the Newcastle-based reality show since 2013.

Her run on the show has seen failed romances to the likes of Aaron Chalmers and Scotty T and she also came out as bisexual in 2016 - making her the show's first LGBT member of the cast. 

And speaking of her desire to cut ties with the show, a source told the publication: 'Marnie has loved her time on Geordie Shore but it's time for her to move on. She will still be around for this series but that's it - she won't return for the next.'
