Ariana Grande has revealed she wishes she had the confidence to go naked like popstar pal Miley Cyrus.

During an interview on Boston radio station Mix 104.1, the Baby I singer had nothing but praise for Mi-Cy, stating her desire to be more like the We Can't Stop stunner.

Speaking of Miley, Ariana said: "I think she's dope. I think she's a rock star.

"I think she's expressing herself, and there's nothing wrong with adding a little fun into pop culture."

When quizzed about Miley's Wrecking Ball promo, the 20-year old confessed: "I wish I had enough confidence to get naked and sit on a wrecking ball. If you had her body, you'd be on that ball right with her."

Earlier this month, Grande also hit the headlines after defending Justin Bieber following his arrest for DUI.
