The retired ballerina was a judge on the BBC celebrity dance contest for seven series between 2012 and 2018 but said she felt pressured by bosses not to behave like a ballet dancer.
Bussell, 53, told the Royal Academy of Dance podcast: "It was really hard because the producers on the show didn’t want me to be the ballet dancer and I was like, 'Well, sadly I am, and I think you chose me because I am the ballet dancer.'
"They were convinced that the public were going to take that on board. But the public did take it on board and [nevertheless] were happy to have me as a judge.
"I was always going to play myself, however much I was convinced that to look like and be like the ballet dancer wasn’t the right thing.

"I was, like, 'Well, sorry, you’re taking me as it is. This is how I look and this is how I’ll act'."
Bussell - who has two daughters aged 21 and 18 with Australian businessman husband Angus Forbes - admitted being a judge on the show was not easy.
She said: "It wasn’t the easiest thing for me, because I wanted to still be the dancer on that dancefloor.
"Being a judge full-time was hard, knowing that it’s live and having the ability to be quick and responsive, because I like to think and take my time."
Bussell became the principal dancer at the Royal Ballet in 1989 at the age of 20. She retired in 2007 and is considered one of the most famous British ballerinas of her time. She was made a Dame in 2018 for services to dance.
