Catherine Tyldesley has become the latest celebrity to be confirmed for this year's Strictly Come Dancing.
Catherine also said she would always "swerve" dance classes at theatre school because she was "really big" and "self-conscious".
She told hosts Eamonn Holmes and Ruth Langsford: "We used to do step routines at school but I'm terrified.
"When I was at theatre school, I always swerved dance classes because I was really big and I was so self-conscious.
"So it's always been a thing to me. I just thought, I need to do this because I've always shied away from it. It's going to be like therapy.
"It's a real challenge for me and it's something I've not been comfortable with."
Catherine previously spoke about her weight and revealed that she was a size 22 when she was a teenager. Aged 18, she weighed 15 stone.

In an interview with Best magazine, Catherine said she would binge eat junk food behind her parents' back.
But after kicking the bad habit, and eating only home-cooked healthy meals instead, she had slimmed down to a size 12 by 19.
Catherine told the magazine in 2017: "When I look at pictures of myself from that time, it doesn’t look like me. I was a different person.
"I actually keep a picture from when I was big on my phone to remind myself just how far I’ve come."
Last year, the actress - who played Eva Price in the ITV soap - revealed she lost weight and toned up by following a 12-week fitness programme.
