Speaking on BBC breakfast this week, Victoria admitted she wasn't finding the physical side of dancing too hard, but couldn't remember the routines!
"It's very challenging. Physically not so much accept the fact my feet don't bend the way they're suppose to - years of being tied in cycling shoes isn't very construtive to standing on your tiptoes!" she said. "But just the mental challenge of remembering the choreography is a whole new skill."
In an emotional interview on the BBC Breakfast series, Victoria also opened up about her earlier career.
The 31-year-old explained how she became so depressed after feeling "unworthy" that she began to self-harm.
"I went through a short period where I was very low, I felt unworthy. People were investing so much time into me, and into something where I didn't think I'd ever be," Victoria told the TV show "I did self-harm, I felt very low. Without [my boyfriend] Steve I wouldn't have achieved what I have in my career."
