The singer may play music festival
Beyoncé is rumoured to be playing at this year's summer festival.
It's been said that the "Single Ladies" star is looking at headlining the Somerset June event after the success of husband Jay-Z's appearance in 2009.
Other headline acts reportedly being booked are U2, who had to pull out of last year's show, and Coldplay.
