And this singer pulled it off with aplomb, taking to the stage at the G.A.Y nightclub in London in the suede over-knee numbers, which she paired with a pretty sequin minidress.
Her large curls were cascading over her shoulders and her makeup was bold and striking. She was also joined on-stage by some bare-chested men sporting festive red trousers.
Leona tweeted her excitement ahead of the performance, writing: "#onemoresleep until I perform at G-A-Y who's ready for Santa?"
The 2006 X Factor winner was joined by a star from this year's show, Hannah Barrett, who, presumably, couldn't believe her luck - and probably picked Leona's brain for some hit-making tips.
