What a busy, busy weekend for the actress! On Friday night, Sienna stopped by W magazine's Golden Globes party at the Chateau Marmont, wearing the Natacha dress from Isabel Marant's spring 2013 collection with red pumps. And on Saturday, she attended the BAFTA Awards Season Tea Party in Beverly Hills, picking a pink Valentino number and nude Louboutins for the occasion. So, which Sienna do you prefer? Boho with a touch of booze-y smile for old time's sake? Or poised and angelic, like she was sent from the heavens?
