The Beverly Hills Hotel brought a bit of old school glamor to the neighborhood Friday evening with the final installment of their Cointreau Summer Poolside Soiree Series. With a dazzling synchronized swimming performance from a bevy of bathing beauties, a live Sinatra-inspired crooner singing the hits, and plenty of Cointreau cocktails flowing, see how the legendary pink and green closed out their weekly event in classic Hills of Beverly style.
