Newly-single Sugababe Heidi Range said her intensive training regime for Dancing On Ice has left her with a "more toned" body.
The 28-year-old singer, who split up with television presenter boyfriend Dave Berry last year, said she was nervous about her first performance.
She 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."
The singer said she had been working on her stomach muscles as she gets ready for the physical challenge of skating.
"I'm still going to the gym. I went after my first costume fitting - I thought 'You're in lycra on HD TV'.
"Since training for Dancing On Ice I have noticed my body changing shape slightly. My legs and my bottom seem more toned, which is good."
