Nick Jonas reveals mortifying moment he ruined Frozen audition

Nick Jonas has revealed he "bombed" an audition for Frozen.

The 33-year-old star has recalled the moment he tried to land the role of Kristoff - who was eventually voiced by Jonathan Groff in Disney's 2013 animated classic - but he had a disastrous experience from start to finish as he turned up totally unprepared.

Appearing on the Hey Jonas! podcast with his brothers Joe and Kevin, he said: “I went in for Kristoff. I went in and they said, ‘Okay, what are you going to be singing today?’

"I said, ‘Oh, I don’t know.’ They said, ‘What do you mean you don’t know?’ They’re like, ‘Do you have your sheet music?’

"And I said, ‘No, no one told me I had…' and so I just said, ‘Can you play something from,’ I don’t know what I said, some musical theatre song.

"And I bombed the audition. It was terrible.”

The Jonas Brothers were joined on the podcast by Frozen trio Kristen Bell (Anna), Idina Menzel (Elsa) and Josh Gad (Olaf).

Bell quipped: "That must have been why you didn’t get it.”

Gad got in on the fun too, joking: "Look, I’ll say it here. You have such better chemistry with Kristen than Groff.”

Nick teased: "I love Jonathan Groff. But I do think it would have been better to cast me."
