The former X Factor star looked gorgeous in the photo, as she proudly flaunted her whopping big diamond for the camera. Her caption read: "OMG guys, got some BIG news to share with you."
Plenty of fans offered their congratulations, while other canny followers noticed that she had tagged in the jewellery company, Warren James Ltd…
And the reason for that soon became clear! Stacey is NOT engaged but rather the new celebrity face of Warren James, teaming up with the store to promote their latest jewellery collections.
"I remember begging my mum to buy necklaces from the store when I was younger. To now be the first ever face of one of my favourite brands is a dream come true. I'm a real magpie – I love anything sparkly – so Warren James and I are the perfect match. Who needs a man when you can have diamonds!" said Stacey.
"Even when I've found myself with a bit more cash to spend, I still want to get the best value for my money so it's always my first stop for jewellery. There's just no reason to pay over the odds. I really hope I can let other people know that actually they can afford precious metals and stunning design in their jewellery. It's available to everyone."
Stacey will front Warren James' Christmas 2015 range, and work with the brand on all of its seasonal campaigns in 2016.
