Despite now being a pop sensation, Ariana Grande hasn't always wanted to be in the limelight.

Speaking to Billboard magazine the Break Free singer revealed her Mum once feared for her future, as she chose sharks over dolls.

"For my fifth birthday party we had a Jaws theme and all my friends left crying. I mean, I still am that way. But when I was little it was more concerning," the 21-year-old said.

"There was a stage, when I was 3 or 4, where my mom thought I might grow up to be a serial killer."

"I always wanted to have skeleton face paint on or be wearing a Freddy Krueger mask, and I would carry a hockey stick around. I was like a mini-Helena Bonham Carter," she added.

Grande went on to explain that although she was bought up Catholic, she has decided to start practicing her own beliefs including Kabbalah, just like her idol Madonna.

"As a fellow Kabbalist, I know how hard it is to exercise those tools in your everyday life," she explains.

"Especially in a world where everything is so egocentric and all you do is talk about yourself and promote yourself."
