Beyonce Rehearsing For Glastonbury At Secret London Location

Beyonce has arrived in London to rehearse for her headline performance at the Glastonbury festival, it's been revealed.

The singer has hired a studio for two weeks in the East End to prepare alongside her backing dancers and stage crew.

“Beyonce is so nervous about the gig she has booked the space for two weeks so she can perfect the set, which will include dizzying pyrotechnics,” a source told the Daily Mirror.

“She’s literally playing with fire. Her performance at Glastonbury is already looking epic.”

The unnamed insider added that the singer was lining up guest appearances by husband Jay-Z, who headlined Glastonbury in 2008, and Kanye West.

Coldplay and U2 are the other Glastonbury headliners. Tickets have sold out.
