The Jonas Brothers may not be making music anymore, but the family still tans together. Joe Jonas and Nick Jonas hit Hawaii with their girlfriends on Monday, relaxing on a Kauai beach. Joe and his girl, Blanda Eggenschwiler, strolled around hand in hand, while Nick and his lady, Olivia Culpo, opted to stretch out across beach chairs and sip tropical drinks while cozied up in their swimsuits. The brotherly duo headed to Hawaii for their former guitarist's wedding, which was seen across all of their Instagram pages. Over the weekend, Nick shared a sweet snap of him and Olivia all decked out in leis, and his girlfriend followed up with a cute one from the photo booth. Joe, however, opted to show off his cupcake, and Blanda didn't post any photos with her beau in them.
