The reality star took part in a Twitter Q&A yesterday evening and fans flocked to her page to ask her all manner of questions - and of course there were a few beauty ones thrown in - she is flawless after all...
Luckily for us make-up obsessives, Marnie revealed that her go-to product at the moment is Laura Mercier's Rouge Nouveau Weightless Lipstick in Malt and that it only sets her back £20 a pop - wahoo!
Judging by her absolutely stunning Instagram selfies (and there are loads of 'em) it's the one beauty buy she swears by for smoochable smackers, and now, we're just as in love with the ultra-sheer nude hue as she is.
To rival Marnie in the pout stakes, grab Urban Decay's Lip Liner in Ex Girlfriend, £14 and trace your entire lip line. Ditch the lip brush and gently dab your Laura Mercier lippie onto your top and bottom lips (a top tip from Kim Kardashian's make-up artist, FYI) - there's no need to blot and re-apply.
Marnie also mentioned that she has fallen head over heels for NARS lately, and we're pretty certain she's a fan of the Sheer Glow Foundation, £31 - how else does she achieve that seamless complexion?
We'll see you in the queue...
