Katy Perry, boyfriend break up

Katy Perry and Florence + the Machine guitarist Robert Ackroyd have ended their romance, E! News said Monday. Perry, 27, instead brought her grandmother to Sunday night's Billboard Music Awards -- where Perry debuted "Wide Awake," a song that appears to address her divorce from comedian Russell Brand: "I'm wide awake," she sang. "I was in the dark, I was falling hard with an open heart. How did I read the stars so wrong . . . Not losing any sleep, I picked up every piece and landed on my feet . . . I don't have to pretend. The story's over now, the end."
