Team GB medallists Victoria Pendleton and Louis Smith are set to take on their next challenge – on the dancefloor.
Pendleton, 31, who retired from her sport after the London Games, had made no secret of her desire to take part in the BBC1 ballroom dancing contest.
Smith, 23, who has hinted that he will not compete in Rio 2016, has already appeared on a previous series of The X Factor.
Fellow sportsman Michael Vaughan is expected to join the two Olympians.
The 37-year-old former cricket captain would follow in the footsteps of cricketers Darren Gough and Mark Ramprakash, who have previously won Strictly.
Other stars confirmed include Girls Aloud singer Kimberley Walsh, Westlife’s Nicky Byrne, Daybreak presenter Richard Arnold and actress Dani Harmer.
Former children’s TV host Johnny Ball, presenter Fern Britton, former Emmerdale actress Lisa Riley, James Bond actor Colin Salmon and actress and singer Denise Van Outen are also expected to complete the 14 contestant line-up.
All of the contestants hid behind Sir Bruce Forsyth masks when they arrived at a south London dance studio for rehearsals at the weekend.
