She looked totally fierce though, right?!
Proving that nudes are still huge news, the Geordie Shore babe - who joined CBB co-star Saira Khan on the panel - showed off her absolutely gorgeous figure in this ultra-slinky cream-coloured one-piece that boasted ribbed detailing along the legs and a low-cut scooped neckline.
Thankfully she managed to avoid an embarrassing VPL situation as she perfected her over-the-shoulder pose for a group of photographers outside - phew!
Making like the Kardashian clan, Marnie slipped her feet into a pair of PVC sandals with a seriously cool perspex heel and she kept of the chill with a stone suede biker jacket that featured lashings of zips, structured lapels and buttoned epaulettes.
She looks absolutely stunning sans make-up, but Marnie refused to face the day without a slick of pink lipstick and her failsafe smokey eye, not to mention a flawless contour - obvs!
Appearing on the show, Marnie played down reports of a split from boyfriend Lewis Bloor, but admitted it has been "tough" as they live so far apart from each other.
Rumours of a split surfaced last week when Marnie deleted all traces of Lewis from her social media accounts, but she cleared up the situation, saying she'd deleted the images after an argument with Lewis.
The star added that they are working past that now.
"It's really tough because we live so far away from each other," she explained.
"We had an argument and I deleted every picture of him on Instagram. I was really angry and immature and forgot everyone can look at it. I thought, 'Why have I done that?! I've put so much pressure on us.'
"It's hard, but we're working through it," she said.
