Beyoncé arrived at L.A.'s Nokia Theatre in a bright orange gown. When she posed with her hand on her stomach, everyone went wild.

The other moment that everyone's talking about came during the opening of the show. Lady Gaga was cross-dressing, appearing as her alter ego "Jo Calderone."
While she performed, Gaga actually fell off her piano. Paramedics were called to the scene but Gaga was fine and went on with the show.

The stars remembered the late Amy Winehouse. Video was shown from one of her very last recording sessions, singing a duet with the legendary Tony Bennett.
