Katy Perry's new song "Roar" just came out and while that one has us dancing, her song with on/off boyfriend John Mayer "Who You Love" has us gushing.

And we're not the only ones! Katy Perry stopped by SiriusXM's Hits 1 to chat about the duet with John and that adorable "love giggle." She also talked about her pal Lady Gaga and how Madonna actually had a huge impact on her career. Check out the video above for all the details and Katy being her adorable self.
