Singer Katy Perry released two new singles this week, including her song "Roar” and her duet with John Mayer, "Who You Love."
The two singers have been dating on and off since last summer. While Mayer confirmed a breakup back in April, Perry told Vogue in June that she still had feelings for her ex, which prompted a reunion.
Perry’s album “Prism” will hit stores in October. Check out Katy's promo for the 2013 MTV Music Video Awards!
