Following in the footsteps of other celebrity M&S spokesmodels, which include Twiggy, Dannii Minogue and Lisa Snowdon, Rosie and Ryan front the new Autograph campaign - the high street store's luxury in-house label.
"I was thrilled when M&S asked me to be in their campaign and Rosie was a pleasure to work with," says Reynolds. "I'm from Canada and grew up with the M&S brand. Going into an M&S store with my family or friends always gives me a beautiful pang of nostalgia."
"I am extremely excited to be working with M&S on the new Autograph Autumn 2011 campaign," adds Transformers actress Rosie.
"I feel proud to be associated with a British high street favourite that holds fond memories for so many people, particularly the Autograph brand, the collection is sophisticated, elegant and effortless which I hope to embody in own my personal style."
The campaign, shot by photographer Greg Williams at the stunning St Pancras Renaissance Hotel in London, sees the genetically-blessed pair showing off some classic Marks and Spencer attire in a 'filmic' style shoot - which arguably, makes the high street attire look decidedly high end.
And it's got us thinking: wouldn't they make a lovely couple?
The new Autograph Autumn/Winter 2011 collection lands in stores nationwide and online on 1 September.
