Katy Perry seemed to have one staple ingredient missing as she stepped out in Los Angeles last night – make-up.

The I Kissed A Girl star was spotted looking au-natural as she dined with friends at the exclusive Philippe Chow restaurant.

The singer, who is currently dating comedian Russell Brand, finished off her casual look with an autumnal jumper dress and thigh-high boots.

Katy Perry appears minus any make-up as she dines with friends.

Perry's decision to appear in public without make-up comes just days after she told followers on her Twitter page that she was worried about a spot on her neck.

“Hope this massive zit on the back of my neck's a good luck sign 4 2night,” the singer wrote.

“Not gonna lie, I always feel WAY more important w/police escorts.”
