The “California Gurl” showed off her curvaceous ‘bod in a tiny black bikini paired with a fedora, and a gorgeous diamond necklace, as she lounged poolside with friends on Thursday afternoon, before digging into the latest issue of Blackbook mag, featuring cover guy Robert Pattinson.

It’s been reported that Pattinson has moved out of the house he shares with Kristen Stewart in light of the cheating scandal, and we all know how much the sexy singer loves the Brits!

Perry had previously been linked with Florence + The Machine guitarist Robert Ackroyd, but the pair haven’t been spotted together in months. Katy is definitely Team Rob!
