The Strictly Come Dancing contestant showed off some cleavage in the racy green number as she took a photo of herself in the mirror.

Beaming down the camera lens, the 28-year-old sizzled as she flashed the flesh in the tantalising picture.

Despite shedding her clothes, the former Saturdays band member made sure she was all glammed up.

Mollie’s blonde tresses were style in tousled waves while she wore some heavy eye make-up and finished off with a touch of pink lipgloss.

The singer captioned the gorgeous shot: “Don’t forget to treat yourself this Christmas girls! I love this Chloe Emerald bra, it’s one of my festive favourites from @bouxavenue. It’s the perfect gift ‘to me, from me’ #mollielovesboux.”

Unsurprisingly, Mollie’s 748,000 followers rushed to like the sexy selfie and many more left a comment to compliment the stunning star.

One person gushed: “Wow, stunningly beautiful. What a Christmas cracker.”

“Beautiful young lady,” praised another, while a third said: “Wow looking gorgeous.”

Later in the day, the blonde beauty remembered to put some clothes on as she enjoyed an evening out with some of her Strictly co-stars.

Mollie spent the night catching up with her professional partner AJ, Gemma Atkinson and Simon Rimmer.

Alongside the snap, she said: “When it’s time for a Strictly reunion already!! @glouiseatkinson @aj11ace @rimmersimon #AlbertsSchloss #Manchester.”
