Although we see Ariana Grande as a sweet pop princess who is coming into her own skin, the "Problem" singer revealed that growing up, she was more on the morbid side of things.

The 21-year-old singer who got her start on Broadway before becoming a Nickelodeon star and launching a music career chatted about what her mom feared would be her future.

According to E! News, while chatting with Billboard's August 23rd issue, Jennette McCurdy's rumored rival explained, "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."

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

Although Ariana Grande currently lives in Los Angeles, she said that she was "a very weird little girl" growing up in Boca Raton, Florida.

She even called herself "dark and deranged," and admitted, "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."

Grande also revealed that she is hypoglycemic. She explained, "When I was a little girl, I would turn into the Tasmanian devil."

Although she was raised Catholic, the "Break Free" artist admitted that she has since "departed from that and started practicing my own things when I was around 12 years old." The brunette beauty now follows in the footsteps of her idol Madonna and practices Kabbalah.

Ariana Grande confessed, "As a fellow Kabbalist, I know how hard it is to exercise those tools in your everyday life," adding, "Especially in a world where everything is so egocentric and all you do is talk about yourself and promote yourself."
