Bradley Cooper sure loves his co-stars!
The two posed sweetly together at the Burnt premiere in London on Wednesday night, making for quite a cute couple!
Too bad Bradley's taken by supermodel Irina Shayk, LOLz!
But Sienna was pretty model-esque herself in a one-shoulder floral Marc Jacobs gown and messy bedhead hair.
B.Coop also looked as sharp as always in a dark suit and slightly spikey hairstyle — his boyish good looks will charm the clothes off anyone! Ha!
