The actress worked tirelessly so she could master the demanding role of ULLA - and loved the experience of singing live.
She says, "The dancing is not so hard for me, but when it came to the singing our musical director PATRICK BRADY helped me to find a voice.
"The good news is they're not having someone else sing for me, so it couldn't be too bad.
"Singing with an orchestra for the first time was also a wonderful experience. I had more fun than I've ever had in my entire life."
