Katy Perry Bikini Pictures Reading About Robert Pattinson

Katy Perry slipped into a black bikini to lounge poolside at Miami's SOHO Beach House today. She was reading the latest issue of BlackBook Magazine, which features her friend Robert Pattinson on the cover. Katy, who is friends with both Rob and Kristen Stewart, has been spotted spending time together with the couple this Spring and Summer, though she is not one of the celebrities who have weighed in on the Kristen Stewart cheating scandal.

Katy has been enjoying a break since promoting her 3D film Katy Perry: Part of Me earlier this Summer. The film didn't draw in big bucks at the box office, but it was relatively cheap to make. Katy nonetheless took home the choice summer movie surfboard at Sunday's Teen Choice Awards. It also seems Katy may have some news in the romance department. It's rumored that Katy Perry's dating John Mayer. The pair were reportedly spotted on a date at LA's Soho House last week, though neither star has addressed the stories publicly.
