Kimberly Wyatt has revealed she has been practising since she was seven years old to be able to stretch her leg over head.
The former Pussycat Doll and Got To Dance judge has made the flexible move her signature pose and dance move and hopes it will inspire others to take up ballet, where she learned to do it.
Kimberly said: "It's tough because it's inspired by some and criticised by others. But I've worked at being able to do that since I was seven years old, through a lot of ballet practice, so I'm very proud of the fact that my ballet basis of dancing is so famous."
The 28-year-old singer releases new single Stars In Your Eyes, with her new band Her Majesty And The Wolves, on January 10 and said she is pleased to have moved on from the Pussycat Dolls.
Kimberly revealed: "I feel free. I'm very happy. I feel like you have one life to live and being self-expressed is such a huge priority that I take quite seriously in my life.
"If I'm not growing then I'm not happy and this project gives me a chance to grow in so many ways: It's challenging, I feel like I get personal victories every day from just trying new things and facing things that maybe don't feel quite as natural but just going for it and putting my heart and soul into Her Majesty And The Wolves."
