Dancing On Ice line-up includes Sugababe Heidi Range
This year's Dancing on Ice line-up includes Heidi Range from Sugababes, singer Chesney Hawkes and actress Jennifer Ellison.
Among the other 15 contestants taking part this year are soap stars Matthew Wolfenden, Jorgie Porter and Laila Morse, Mo Harris in EastEnders.
Former Olympic champion Katarina Witt and choreographer Louie Spence join Robin Cousins on the judging panel.
They take over from Jason Gardiner and Emma Bunton, who have left the show.
Karen Barber continues as head coach.
Sugababe Heidi Range said her intensive training regime for Dancing On Ice had left her with a more toned body.
The 28-year-old singer said: "I'd love to get to the stage where I'm performing and enjoying it, rather than just feeling nervous.
"It's great now that we're at Elstree more and we keep bumping into everyone - it's really nice, it's like a little gang now and I'm enjoying getting to know everyone.
"I've had the chance to spend time with Jennifer Ellison and Jorgie Porter, which was really nice."
Among the other celebrities taking part in the show are Dallas actress Charlene Tilton, 1980s actor Corey Feldman, fitness guru Rosemary Conley, children's TV presenters Sam Nixon and Mark Rhodes.
Founder of freerunning Sebastien Foucan, skier Chemmy Alcott and Coronation Street star Andy Whyment make up the 15.
The show this year is hosted by Phillip Schofield and Christine Bleakley, who replaces Holly Willoughby.
Dancing on Ice 2011 was won by former EastEnders actor Sam Attwater.
The seventh series of the ITV1 programme begins at 6.30pm on Sunday 8 January.
