The 28-year-old songstress, whose real name is Jessica Ellen Cornish, said Grande deserves all the success in the world because she works so hard, reported Female First.
"I'm so proud of her, she works so hard. Music is a feeling, and there are some people that can put how you feel into a lyric, and a melody to a lyric.
"And I think that's the beauty of music, and I think it can take you to a place that not everyone knows how to be taken to. I think musicians are able to create a feeling in three minutes that someone needs for a lifetime," Jessie said.
