A-lister Kate Winslet has ramped up the glitz and glam to address the "heartbreaking" situation of youngsters living rough.
The Oscar-winning actress was hosting a fundraiser in the heart of the City of London in benefit of Cardboard Citizens, a charity which gets the homeless involved in theatre.
With 170 guests attending, the 38-year-old donned a Beaton's Atelier ball mask to match the event's theme of secret beauty.
Wearing a Helmut Lang jacket and Roger Vivier shoes, she was joined by the likes of artist Tracey Emin and Kinks frontman Ray Davies. Guests were invited to bid in a charity auction for luxuries such as afternoon tea at Claridge's, a bespoke Burberry trenchcoat and a sculpture made with quartz crystal.
Speaking about her work as a patron for the charity, Winslet said she had been attracted by how it uses creativity to turn troubled lives around.
She said: "Anyone has the capacity to act and to express themselves, it's just that they don't always know how to do that or have the means to do that."
Asked if she had ever been forced to sleep rough, she said: "No, I haven't, but of course homelessness should be important to all of us. It's a terrible situation that any young person should be homeless and should have something that they had to run away from.
"I'm no different to anyone else, it's a heartbreaking prospect and I think what Cardboard Citizens is doing to help to change that and to encourage a different type of life for homeless individuals is really, really special."
Speaking about her latest project - a period drama called A Little Chaos directed by Alan Rickman, Winslet indulged in a traditional British pastime - moaning about the weather.
She said: "I'm filming at the moment, we are halfway through actually. It's a lot of hard work, as every film is, but we're having a lot of fun. I think we just wish the sun would come out a little bit more for us than it has done so far. We're filming and the UK and it's just cold."
