London: Pop star Katy Perry is all set to perform magic tricks in her upcoming US tour and has signed an agreement with magicians to refrain from divulging their secret techniques.
The 26-year-old singer said that she was impressed by a magic act on the reality TV show `America`s Got Talent` and instantly planned to incorporate it into her forthcoming California Dreams tour, reported Contactmusic.
The `Fireworks` hitmaker has also hinted about being tight-lipped on the entire process on the request of the two performers.
"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," said Perry.
