In a recent interview with Rolling Stone, Grande revealed what the most embarrassing moment of her career was to date.

Back in 2011 she kicked off her music career with the single "Put Your Hearts Up." This was before Justin Bieber's manager Scooter Braun signed her back in 2013.

"It was geared toward kids and felt so inauthentic and fake," she explained. "That was the worst moment of my life. For the video, they gave me a bad spray tan and put me in a princess dress and had me frolic around the street. The whole thing was straight out of hell. I still have nightmares about it, and I made them hide it on my Vevo page."

Entertainment Wise added that Grande also explained that music has always been her passion first and foremost, and she was never this connected to acting.
