The reality starlet - who lives by the mantra 'If you've got it, flaunt it' - has taken to Instagram to give us a glimpse of her perfect figure, having shed her clothes to pose in a pair of racy lacy white undies.
And there's no denying she looks hotter than ever.
Marnie just launched her first ever clothing collection with online fashion hub Forever Modo, but proved that you can't beat lounging around the house in your undies once in a while. The difference between us and Marnie, however, is that we probably wouldn't want the whole of the Internet to see!
Major kudos, Marns.
In the raunchy snap, the confident starlet dons a super-sexy multiway bra and a matching pair of barely-there knickers. She shows off her incredibly taut gym-honed tum (jealous? us?) and her slender, catwalk-worthy pins that could probably give Kendall Jenner a run for her money.
The stunner rocks a big bouncy blow-dry and minimal make-up and takes the picture on a chunky camera.
Last week, Marnie bared all as she posed completely nude in her living room before sharing the picture to Snapchat. Three heart emojis hid her modesty from the camera, but it was plain to see she had given her bra and knickers the elbow.
Marnie's very daring snaps come after she decided to get real honest about her sexuality. The Geordie Shore beauty revealed she is bisexual and spoke candidly about an earlier encounter that she had with a girl that made her realise she was attracted to both sexes.
Marnie said: "I don't think I took it seriously until I had an encounter with a girl last year. To me, that was different because it was just me and her. It wasn't for any other reason than I wanted to, so it made me think differently."
