Beyonce has revealed that her husband Jay-Z and mutual friend Coldplay frontman Chris Martin approved her set list for the Glastonbury Festival.
The US singer closed the annual Somerset event on Sunday (June 26) – three years after Jay-Z topped the same bill.
"I sent Chris my set list and made sure he approved it," Beyonce told the BBC after her appearance on the Pyramid Stage.
"He's the master of this and of course, Jay. They all just told me to relax and be myself."
Beyonce also admitted that she didn't think she would have been asked to perform at the festival if it hadn't been for Jay-Z's appearance.
Meanwhile, the singer previewed songs from her new album '4' in front of a star-studded audience at London's Shepherd's Bush Empire last night (June 27).
