Kim Kardashian was all about the bikini time yesterday, kicking things off in her white and tan suits at a photo shoot. She switched into a teal two-piece and then one in purple to join her similarly skin-baring sisters Kendall, Kylie, and Kourtney for even more poolside lounging. Mason Disick was the lone male along for the afternoon, though he stayed relatively covered up in his adorable sun hat. While Kim was showing off her fine form for the cameras, her friend Nicole Richie was up to some April Fools' hijinks back in LA. Nicole took over Kim's Twitter account to send silly messages like, "I wish I was Joel Madden."
