Strictly star Mollie King has set pulses racing on Instagram by sharing a snap of herself in a bra in a promotion for lingerie company Boux Avenue.

The 30-year-old singer of the Saturdays stars in the new advert for the British fashion brand, which is owned by Dragons' Den star Theo Paphitis.

King sings as she parades around the TV commercial in just her underwear.

Some of her 748K followers were quick to comment on the revealing mirror snap of her in a lacy green bra. One wrote: "Hot or what stunning."

Someone else said: "you're unreal."

A third added: "Wow, stunningly beautiful. What a Christmas Cracker."

King, who is rumoured to be dating her Strictly pro dance partner AJ, 23, proved she's still close to the other stars of the series as she shared a reunion snap with the likes of Gemma Atkinson, Simon Rimmer and her reported love interest in Manchester:

King and AJ were a popular pair on the series but are said to have been snubbed from the Strictly Come Dancing live tour, which begins in January.

The duo failed to impress judge Craig Revel Horwood on the dancefloor, especially after he dubbed the singer "awkward and wooden" in a previous live show.

King and AJ allegedly "had no chance" of featuring in the tour with Horwood involved, the Mirror claims.

King's fellow celebrity dancing contestants Gemma Atkinson, Alexandra Burke, Susan Calman, Davood Ghadami, Joe McFadden, Debbie McGee and Jonnie Peacock are set to perform in the 30-gig live tour with their pro dance partners.

It will kick off in Birmingham on 19 January. Horwood will be joined by Bruno Tonioli and Darcey Bussell on the judging panel. Last year's winner, BBC presenter Ore Oduba, will host.
