Former South African President, Nelson Mandela, celebrated his 90th birthday in style at a massive concert in Hyde Park in London on Friday night.
Stars including Leona Lewis, Amy Winehouse, the Sugababes and Will Smith joined Mr Mandela live on stage.
As well as celebrating his birthday, the gig also raised cash for charity.
Mr Mandela is one of the most famous men in the world, and spent years in jail campaigning for the rights of black people in South Africa.
The birthday bash wasn't just about having a big party - the gig was also used to promote freedom for all.
Mr Mandela, who was introduced on stage by Hollywood actor Will Smith, told the crowd: "Even as we celebrate, let us remind ourselves that our work is far from complete - our work is for freedom for all."
Since Mr Mandela retired from politics nine years ago, he has campaigned around the world for peace and an end to poverty.
