Sienna was in Beverley Hills last night, attending the Annual International Medical Corps Awards Celebration, at which she was honoured for her work with the charity! She looked fresh, pretty and sophisticated in a little black dress, ankle boots, and her hair in a (very large!) bun – I think she looks fantastic, and very appropriate for such an event. It was a great honour for her to receive this award, and I’m sure she’s very proud! Sienna says that the International Medical Corps is a cause very close to her heart.

I’ve added almost 150 photos of Sienna looking gorgeous at the event, including over 60 HQs. Enjoy the photos, and then head on over to InternationalMedicalCorps.org to read more about their work and what Sienna does with them.

On receiving the award, the blonde beauty said: “After seeing International Medical Corps’ courageous work up-close I was determined to become more involved. These people work in the toughest conditions imaginable, saving lives every single day, and bringing self-reliance and hope to the world’s most vulnerable people. I am honored to be their ambassador.”
