The professional dancer - who is paired up with rugby player Ben Cohen this year on the BBC competition - recently flashed her toned figure and stripped down to a sheer black bra and matching underwear for the Cosmopolitan Lingerie Show in aid of Breast Cancer Awareness Month.
We never knew that doing the Waltz and the Charleston could give you such killer abdominals!
The lingerie show was thrown for Breast Cancer Awareness Month's 'Coppafeel' campaign and sees Kristina modelling alongside a handful of women each in their own figure flattering bras.
The Russia-hailing pro is currently working up a sweat in dance rehearsals with Ben, in preparation for Saturday night's Strictly show.
And no doubt both stars are hoping to go far in the competition - especially since Kristina likes to reward herself with some retail therapy after each series ends!
Last week she told The Telegraph: "After a Strictly season, or maybe after finishing a tour, I'll treat myself to a beautiful dress, a nice purse or some expensive shoes. That makes me feel good because I've worked really hard for it.
"When I was young I never had the luxury of new clothes so now it makes me feel good that I actually can go and buy some beautiful items. But I'm still sensible, I'm not going to go and buy something for several thousand pounds. That is never going to happen."
