Beyonce gave fans a huge surprise at the Sound of Change concert in London last night (01.06.13) when her husband Jay-Z joined her on stage for a rendition of their hit song 'Crazy In Love'.
The couple - who together have a 16-month-old daughter Blue Ivy - performed their huge hit 'Crazy In Love' much to the delight of the crowd at London's Twickenham Stadium.
They even shared a kiss on stage in front of the adoring fans at the show in aid of The Chime For Change charity which funds education, health and justice projects for women.
Appropriately opening her set with 'A Change Is Gonna Come', the superstar led the crowd through a set filled with hits like 'If I Were A Boy' and 'Single Ladies'.
She also paid tribute to the late Whitney Houston - which was also done on her Mrs Carter Show World Tour - saying ''We will always love you, Whitney'' during a performance of 'I Will Always Love You'.
Beyonce then brought her headline performance to an end with the ever-powerful 'Halo', closing a hugely successful event.
She told the crowd earlier in the show: ''This is such an incredible night for all of us. Because of you all, we have raised more than $4 million.''
She had spoken about the show and the charity, adding it was vital for women with a high profile to help those in need.
She said: ''Womens' rights, it's something that has always been something close to my heart. I know now being a mother it is really important that I can do what I can and use my voice.
''There are women around the world that don't have a voice so we have to use our voices and raise awareness and be part of something where we can leave a legacy and help improve this world.''
