Sienna Miller and Tom Sturridge get romantic in Burberry campaign

Sienna Miller and her boyfriend Tom Sturridge have shown off their relationship in a steamy new advertising campaign for British fashion house Burberry.

The usually private pair, which is parents to daughter Marlowe, is seen up-close-and-personal in the stylish black and white shots, which were snapped by celebrated photographer Mario Testino.

In one picture, Sturridge grabs Miller's leather-clad backside, while in another, the couple kiss behind a Burberry bag.

Burberry designer Christopher Bailey says, "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."

They are the latest Brits to pose for the brand, following in the footsteps of Emma Watson, Kate Moss, Eddie Redmayne and Cara Delevingne.
