Beyonce has apparently recorded a duet with Bruno Mars. According to recent reports, the pair have hooked up to perform a track, which is set to feature on Jay-Z's joint project with Kanye West, Watch The Throne. The song is rumored to be called Lift Off, and could be released along with the album this summer. The Destiny's Child star is thought to have asked Jay-Z and Kanye West to appear on stage with her during her headlining performance at Glastonbury Festival this year.
