ET enjoyed talking to Katy Perry so much that it didn't seem right not to share some of the fun, so we let some of the Roar singer's famous fans ask the pop princess some of their burning questions.
"Are you happy?" Cher asked via video. "Are you having a good time? Because that's what it's all about."
"Yes!" Perry said, admitting that she was honored that Cher was even aware of her existence.
Kirstie Alley got in a fashion question, saying, "Do you have to bleach your hair before you make it blue? Because I'm dying to have blue hair."
Perry advised using a wig since the bleaching process is necessary but also potentially damaging.
NCIS star Michael Weatherly got the most surprising answer out of the 28-year-old superstar when he inquired about her dessert preferences.
"I'm a salt person," confessed Perry, who turned heads with her scantily clad dessert-themed outfits for her California Gurls video. "I prefer a baked potato over a cupcake."
Perry's latest album, Prism, drops October 22.
