Though stars like Beyoncé, Sofía Vergara, Russell Wilson, Serena Williams, Chris Hemsworth and Jane Fonda were blessed with bootylicious bodies at birth, they don’t maintain their fantastic physiques by sitting on the couch eating Cheetos and watching Real Housewives reruns! Whether sprinting down the field, squatting at the gym, sweating the day away at SoulCycle or engaging in hard-core lunges al fresco, these singers, actors, athletes and models bust their butts to get their backsides as close to perfection as possible. LivingHealthy has chosen 16 controversy-free celebrity bootys (none of these stars have been accused of artificially plumping up their posteriors) and uncovered the butt-blasting workouts they undertake on a daily basis to earn their bootyful bodies.
