Beyoncé will make her Glastonbury Festival debut amid heightened security measures tonight.

Sources close to the singer have confirmed that a “ring of steel” was put up after fears that stalker Bassey Essien, who has already been hit with a restraining order, may be at the festival. She will have almost double the security of other headliners U2, Coldplay, Queens of the Stone Age, and Plan B.

Beyoncé, who has been rehearsing for three weeks ahead of her performance, fell in love with Glastonbury after watching husband Jay-Z take to the pyramid stage at the festival in 2009. Her love of the festival certainly hasn’t faded as she has been shown dancing along to Coldplay‘s hour-and-a-half set in BBC television coverage of the festival. Coldplay frontman Chris Martin is said to have tipped the scales in Beyoncé’s decision to play the festival.

The “Bootylicious” star will be bringing the three day festival to a close tonight, one of only three women to do so in the festival’s 40-year history.

Glastonbury founder Michael Eavis said on Sunday “She’s going to be brilliant”, before fueling rumors that she will be joined on stage by her husband Jay-Z, saying “I wouldn’t be surprised, would you?”
