The reality star's engagement to former TOWIE star Ricky Rayment was caught on camera for the upcoming series of the MTV show, so the whole world will be able to watch the very private moment.
Speaking to Daily Star, she admitted: "At first I was annoyed that it was being done on camera and MTV were getting to film the most special moment of my life. I would have preferred them not to be there. But I realise I am a reality star and I've done everything else on camera so why not this?"
Ricky popped the question in Greece while Marnie was filming the new series of Geordie Shore, which will air on MTV from next month.
Ever the romantic, he treated Marnie to drinks on a cliff top at sunset and proposed via the words 'Will you marry me?' written in the sand below in flames. We cannot WAIT to see this episode!
And now that the engagement is out the way, next up is marriage… then kids! Marnie added: "I'd have the wedding on camera. I'd even have babies on camera. Why not? It would ne nice to have the footage to look back on in years to come."
The engagement happened way back in June but Marnie didn't officially confirm it until this month – these guys really know how to keep a secret!
Marnie's interview with Daily Star was published the same day she hit back at rumours the engagement had been called off. Speculation of trouble in the romance began over the weekend when Marnie was seen partying with a "mystery man" and not wearing her engagement ring.
But all is fine in the Marnie-Ricky world, as she took to Twitter to reveal the mystery man was actually an old friend who is dating her best pal, and that the ring had simply been left at home!
