Beyonce Knowles stuck with a one piece instead of a bikini, but still showed off her amazing curves yesterday afternoon when she hit the beach in Hawaii. She and Jay-Z headed West earlier in the week for a family vacation with her nephew Julez, after a fun and music-filled weekend together at Coachella. Jay-Z was in a pair of appropriately floral swim trunks to document their day by the water, and he was there to snap photos as Beyonce let Julez bury her in the sand. Their trip gives Jay-Z a chance to rest a few weeks before he has to start prepping for his May 8 appearance on SNL.
