Katherine Jenkins Can't Stop Smiling As She Struts Her Stuff In London

Check out that smile! It seems Katherine Jenkins had a good night out on the tiles because she couldn't stop grinning as she left a London restaurant.

The opera singer looked delighted, and we wonder why - was it her retro dress/biker chic look? Or was it just the satisfaction of a good meal? Well she was spotted leaving restaurant C. London.

The Welsh beauty combined a grey 60s style dress, which fell to the middle of her calf, with a black leather biker jacket and a pair of ankle boots.

For the beauty, she went for a touch of pink around the eyes and a glossy lip.

More Katherine?! Well here are some of her best Instagram snaps.
