The singer, who hit the road with Swedish pop star Robyn earlier this year, told MTV News that far from dishing out advice to Robyn she actually tried to get tips on being hip from her.
'I don't need to give her advice,' Katy said. 'She needs to give me advice. She's cool, dude. She makes everyone cooler... She's just, like, the epitome of effortless cool, like you look at her wardrobe and you think, 'I don't think I could wear that,' but she wears it and she just owns it.
'She's always wearing platform shoes, whether it's, like, creepers or Prada shoes. And she was wearing them way back when, in the beginning of the tour. And now Prada's doing them, everyone's wearing them. Rihanna's wearing them. I'm wearing them after all of the convincing, so she's kind of the tastemaker. It's gonna be a great show because of that.'
