Capsule: Star Island, a man-made island in Biscayne Bay, has for decades been one of the most exclusive addresses in Miami. Home to some of Miami's wealthiest residents and celebrities that include Gloria Estefan, Sean (P. Diddy) Combs and Rosie O'Donnell, Star Island's newest star resident is Miami Heat center Shaquille O'Neal. The island is reached by a bridge that runs from an exit off the MacArthur Causeway.
