Katy Perry says daughter Daisy "loves seeing Mama get ready" for her Vegas show: "It's a great routine"

One reason Katy Perry wanted to have a Las Vegas residency is because it gives her more time to spend with her 16-month-old daughter, Daisy Dove.  Now, Katy says Daisy is a big part of her preparation to hit the stage.

"Daisy's with me all the time and she loves seeing Mama get ready and turn into the character," she tells People magazine, referring to the fact that she portrays a doll in her residency show PLAY. "And I get to give bath time between 6:00 and 7:00. It's a great routine. I thrive on routine."
