• Leonardo DiCaprio and Charlize Theron were enjoying separate nights out when they saw each other hanging at Teddy's inside the Hollywood Roosevelt Hotel. The actress and her girlfriend were invited to join the Inception star and his pals at their table. According to an onlooker, the vibe was polite and sweet, and Theron introduced herself to the table with handshakes and hellos. Conversation flowed and everyone laughed, seemingly having a great time. Theron snuck out before other guests, though not before giving DiCaprio a hug goodbye.
