The former Made In Chelsea star posed next to a chicken and it looks like she's covering her, erm, modesty with a tray!
Her toned tum and golden tan definitely caught our eye.
Is naked cooking going to become a thing? What happens if you spill something hot?!
However, if you take a closer look you'll spot a nude strap which we reckon means Millie has got a bikini on.
Phew… hot spillages issue averted.
Though it wouldn't have been the first time Millie's gone for the topless option recently.
Millie looks like she was taking time out from sunbathing to knock up her dinner on Saturday (9 August).
The star revealed: "My husband has just had his hand up another birds a****."
Charming! To which her hubby Professor Green replied: "And you loved it."
However, the cooking sesh wasn't quite up to Celebrity Masterchef contestant Millie's usual standards. She shared another snap of the finished item, which looked a little bit burned.
Millie said: "Ok so we were following an American recipe.. #chargrilled #oooops."
The cute couple were cooking up a storm in their new kitchen and Pro was seriously excited by the rotisserie equipment he's had installed in there.
So excited, in fact, that he posted a video... Of the chicken being cooked.
We especially love Pro's happy face at the the end. Watch it here...
The rapper said: "possibly the best Instagram video I'll ever post #spitroast #rotisserie #gaggenau."
