Katy Perry will turn a magic trick when she picks up her California Dreams tour on 7 June (11) after agreeing not to reveal how the illusion is done.

In a new Entertainment Weekly interview with support act Robyn, the I Kissed a Girl singer reveals she was so impressed by a magic act she saw on reality TV show America’s Got Talent, she asked how the trick was performed – and now she has incorporated it into her live show.

She explains, “I saw these two magicians do it on America’s Got Talent… and I thought, ‘I’ll have them teach me the trick.’

“I had to sign a nondisclosure agreement saying that I wouldn’t give away the secrets behind the magic trick.”
