The campaign, which will launch in Burberry stores globally on 3 July, was shot by Mario Testino and includes outdoor and print ads. Additional video and behind the scenes content will be revealed across Burberry's online and offline channels.
Digital activity will run on Burberry.com as well as social media channels such as Facebook, YouTube, Twitter, Google+, Instagram, Pinterest, Polyvore, Sumally, Sina Weibo, Douban and Youku.
The AW13 campaign launch follows last month's digital brand campaign, Burberry Kisses, in partnership with Google. It is the brainchild of Christopher Bailey, Burberry's chief creative officer.
Bailey said: "This was a shoot full of love and laughter. It was such a treat to work with Sienna and Tom, and to capture their magic together."
Tom Odell was again chosen to provide the soundtrack for the video, with a special version of "Hold Me" recorded live at the Burberry Prorsum Womenswear autumn/winter 2013 show.
