Sienna Miller and Tom Sturridge for Burberry AW13

As if we needed any more proof that Sienna Miller and Tom Sturridge are the hottest British couple around, Burberry has gone and cast them as its smouldering new campaign stars for Autumn Winter 2013.

Giving a nod to the heart motifs which adorn much of the coveted collection, the lovestruck duo can't keep their hands off each other as they pose in classic black and white shots for renowned fashion photographer Mario Testino.

While we're used to seeing this twosome all effortlessly boho with matching topknots, ripped jeans and baby Marlowe in tow, they've seriously upped the glamour ante, looking slick for Burberry's campaign shots. In the accompanying video they work classic camel trenches and quilted leathers as well as statement ponyskin shoes and bags, all aptly to the tune of Tom Odell's Hold Me.

Burberry sums up: "It’s a bit of a love story and continues our couple concept, which has become synonymous with the campaigns over the years." Indeed, Christopher Bailey has cleverly paired the likes of Cara Delevingne and Eddie Redmayne, and Rosie Huntington-Whiteley with Sam Riley for campaigns in recent years, though we think it's a stroke of genius putting real-life couple Tom and Sienna behind the lens.

And proving there was no acting required, the pair were pictured recently looking just as loved-up at Glastonbury Festival, no doubt basking in the glory of their fashionable work for Burberry.
