American Idol fans have turned on long-time judge Katy Perry, and have demanded she be replaced by a new guest judge.
Katy, who was in the UK to perform at the King's Coronation, was replaced by Ironic singer while she appeared at the historic event.
Meanwhile, Lionel Richie, who is also a judge on American Idol and was invited to perform for King Charles, was replaced by British pop star Ed Sheeran.
