Singer-actress Miley Cyrus is not too young to be a celebrity mentor on American Idol, according to one of its producers.
The Hannah Montana star, 17, recently appeared on the US talent show to help mentor the contestants.
But her appearance drew a barrage of criticism, with many complaining that Cyrus is too young to be a mentor.
Now the show's executive producer, Ken Warwick, has spoken out in her defence.
He said to celebrity website People.com: 'Miley brought an amazing, youthful energy while working with the Idol contestants this past weekend.
'Her experience in the music industry and her advice in handling fame at a young age proved invaluable.'
He added: 'All of our contestants use what they learn from the mentors each week to carve their own path in the competition and Miley was no exception to this.'
