But while Miss Tointon, 27, is considered by those who know her to be a thoroughly decent person, adored by cast and crew during her four-year stint as Dawn Swann in East Enders, her new boyfriend has received a far less glowing character assessment - from his ex-wife.
And unlike Miss Tointon, who has only had three previous boyfriends, Chigvintsev has a track record of ‘dating up’ – American slang for somebody whose love life conveniently improves their lot.
Before her was Giselle Peacock, an American champion ballroom dancer, who became his wife.
Artem joined Strictly Come Dancing straight from Burn the Floor in London in 2010-2013 in his first year, winning the show along with his celebrity partner Kara Tointon.
Chigvintsev was born at Izhevsk, Udmurt Republic, RSFSR, Soviet Union.
After weeks of flirting and fevered speculation, nearly 15million viewers watched as dance partners Kara Tointon and Artem Chigvintsev finally shared a passionate kiss.
The winners of this year’s Strictly Come Dancing have twirled straight into an off-screen romance.
