Helena Bonham Carter, Colin Firth and Damian Lewis were just some of the stars who joined Save The Children for a night of reggae and fundraising.
The Harry Potter actress donned multi-coloured dreadlocks and turned out to the event at London's Roundhouse where guests were treated to live performances and an auction that raised over £1.4 million for the charity.
Other famous faces who came out to support the event included Sir Michael Caine, Helen McCrory, Dominic West, Jon Snow, Ali Bastian, Alexander Armstrong and Helen Fielding.
Performers on the evening were Ernest Ranglin, Jimmy Cliff, Sly And Robbie, Suggs, Ali Campbell, Dawn Penn, Max Stone and Elli Ingram.
Dawn and Ali performed I Got You Babe with Sly And Robbie, who also joined Suggs on stage for Cecilia. Many of the night's performers then got up to play It Must Be Love with Suggs.
Helena, who co-hosted the event with chairman of the charity Sir Alan Parker, said: "[Save The Children] seem to have been pretty effective at raising a great deal of money to save children's lives. Children are vulnerable throughout the world... For me, it's a privilege to be able to try to do something to make a difference."
Suggs said of the performances: "It's not just a roll call of famous faces. It has a coherence and the fact that artists are playing some of their more famous stuff and some of their more obscure stuff that they love, I think the audience are getting a much more authentic night of music than they would if it was just one star after another."
Jon Snow added: "I've met Save The Children in all sorts of places, from Haiti to Kashmir, Syria to Afghanistan. Just rock on, let's keep going because there's so much to do.
"This is beyond politics, this is life, and that's what we're about, and we've got to connect and do."
The auction included a Marc Quinn painting that went for £150,000, a private dinner for 12 with Harry Redknapp, a luxury holiday to Jamaica and a portrait of Bob Marley by Alex Young of Heavy Artillery Crew.
