The Doctor Who star, 32, gazed adoringly at his actress girlfriend and cut a smart figure in black jeans and a quirky black and red satin shirt.

Meanwhile Lily, 26, who is starring in Pride and Prejudice and Zombies alongside her beau, looked stunning in a black and pink checkered dress, which clinched in at the waist.

Adding height to her already slender frame with a pair of classy black heels, the Downton Abbey star ensured her make-up was immaculate as she arrived at a photocall for the film later in the day.

The brunette kept her glossy locks down and she completed the look with a simple chain bracelet.
