Jay-Z to perform with Beyonce at Glastonbury 2011?

Jay-Z and Kanye West 'look set' to perform with Beyonce when she headlines Glastonbury 2011, says one tabloid source.

The singer is also reportedly so nervous about playing Worthy Farm, where she is due to bring the event to a close on the Sunday (26 June) night, that she has rented a London studio for extra rehersals.

A source told the Daily Mirror: “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.”

They added: “Her performance at Glastonbury is already looking epic. She’s been given a helping hand by Jay-Z and Kanye West who both look set to perform songs with her.”

Other headliners U2 might face protests while performing on the Friday (24 June) night, with Coldplay expected to debut new material after airing new song ‘Every Teardrop Is A Waterfall’ recently.

Glastonbury Festival 2011 tickets have sold out.
