Ariana Grande used to impersonate Judy Garland

Ariana - who plays Glinda in the new 'Wicked' film - told W Magazine: "I used to sit in front of the TV in my little gingham dress and study Judy Garland's body movements, how she held herself and Toto. My first impersonation may have been Judy Garland.

"I've always had a fascination with sounds and tones and different accents - my first memory is singing with my mom in the car to Barbra Streisand or *NSYNC or 'Over the Rainbow'. I don't remember a time when singing wasn't a part of my life. Strangely, I remember watching 'The Wizard of Oz' in the gingham dress paired with a 'Scream' mask."

Ariana previously admitted that she's always found an "escape" in musical theatre.

The actress revealed that she's always loved the "storytelling" element of theatre shows.

She told Variety: "I mean, it was just something that spoke to me.

"I was a child, and I would sit there watching 'The Wizard of Oz' and study Judy Garland, and I just remember it being such an escape. I loved the storytelling and seeing my first Broadway show."

Ariana fulfilled a long-held ambition by starring in the 'Wicked' film, and she's recalled "hunting" down an opportunity to audition for the movie.

She said: "As soon as I found out that it might be happening, I told my team, 'Be on high alert, please. And I know this has to be earned. So when they start seeing people, can I please go in? I'll do anything.' And I worked really hard with a vocal coach and an acting coach to get ready, because Glinda's vocal track is very different than what I usually sing."
