The supermodel has recruited her friend Timmy Mallet to host the December 17 event at her home in the Cotswolds, according to the Daily Star.
"Kate loves all the glitz and glamour of Strictly, so she has decided to host a Strictly-themed party," a source said. "She's invited 17 of her close family friends and told everyone to dress up to the nines."
Among the guests apparently invited to Moss's Strictly bash are Stella McCartney and Fazer from N-Dubz.
"It will be a very glamorous affair, all of the girls in silk, ballgown-style dresses and the men in formal dinner jackets. Kate loves singing and prancing around so it'll definitely end up in a karaoke session.
"We're not sure if Timmy will be sporting one of his wacky loud shirts, colourful glasses or giant pink foam mallet but it's guaranteed he'll sing on the karaoke with Kate."
