Jay Z joins Beyonce on stage during concert

Pop star Beyonce Knowles gave fans a huge surprise at the Sound of Change concert 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, reported Contactmusic.
They even shared a kiss on stage in front of the fans at the show in aid of The Chime For Change charity which funds education, health and justice projects for women.
Opening her set with 'A Change Is Gonna Come', Beyonce 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.
