In terms of dollars, the Katy Perry brand looks solid: The dreamy dance-pop album Prism is her third to go platinum, and her Prismatic World Tour — now hitting the West Coast — was the best-selling stadium romp of the summer. But in her personal life, she’s dealt with some downers: a divorce (to Russell Brand), a breakup (with John Mayer), and a rather unfortunate VMAs outfit (denim, with Riff Raff). Luckily, she has plenty of pals and staffers around to help keep her spirits up. Some of her BFFs, including Rihanna, Mia Moretti, and Shannon Woodward, are quite visible on her Instagram and Twitter — and other known associates are on her frequently on her arm at parties.
