SIENNA MILLER’s new role? Drama queen!
The British actress and her “Brothers & Sisters” beau BALTHAZAR GETTY stopped by the Chateau Marmont on Aug. 16.
Everything seemed fine until Sienna got up and huffed: “I’m leaving!”
She stormed off and ducked into the ladies’ room.
After waiting for 30 minutes, Getty decided he’d had enough and bolted from the hotel – solo!
