LILY ALLEN had another run-in with a photographer this week after the feisty singer got a little drunk on a night out in London.

The 22-year-old stubbed out a cigarette on the camera lens of one paparazzo as part of a drunken night out with supermodel KATE MOSS.

Having quaffed free wine for much of the night, the LITTLEST THINGS singer performed a secret gig for the launch of the Braun Satin haircare range in London.

However, the pint-sized popster was a little worse for wear and struggled to remember the lyrics to her songs.

“What day is it?” she asked the crowd after two songs, before going off on a tangent about her hair.

She slurred: “Look at my hair, it’s so f******g straight, I wish I was as straight - I’m a bit drunk.”

She then added: “Are you enjoying the free wine, I know I am.”

The singer then carried on at the Groucho Club with Kate Moss, partying until the early hours of the morning.
