The 23-year-old said she is obsessed with sky-high shoes and wears them to perform as they give her more of a star presence, reported Contactmusic.
"I've been training in heels since the age of 14 as my sister once said to me, 'If you really want to be a super star like Beyonce, then you're going to have to be able to dance in heels.
"When I put heels on and I go on stage it completely changes everything about me and I turn into that... That beast, and it really is because of a heel. I won't go on stage without a heel on," she said.
