singer boasted to other stars backstage about having the chopper ready to fly her out at a moment's notice this weekend.
Singer Florence Welch of Florence and the Machine said she told Lily: "Wouldn't it be amazing if you actually had a helicopter on standby when you clicked your fingers?"
According to Britain's
newspaper Lily replied: "That is my reality. The heli is ready to go when I want. I thought I'd get one in case I get 'the fear'."That way I can do my crying away from prying eyes on the way home."
Lily, 24, reportedly had the helicopter on standby in case she wanted to leave the event if she became too upset over the anniversary of her grandmother's death.
Last year she also had a helicopter to take her to the festival, courtesy of her collaborator Mark Ronson.
The super producer had jokingly offered Lily "anything you want, a car, a driver, a helicopter" when she agreed to join him on stage at the event but was stunned when her assistant called him with a £5,000 quote for the helicopter she had booked.
Mark said: "She completely took me seriously! And what was I going to say at that point? I had to pay for it. She got the helicopter."
