Charli XCX has opened up on some of her more off-kilter festival experiences.

The singer - who is playing the likes of Wireless and Bestival this year - told the Guardian about her take on festivals.

When asked what her worst drug experience at a festival has been, the Brit replied:

"Oh, gosh. I remember I was at the Secret Garden Party and I peaked, let’s say, very quickly and had to sit on the floor in the middle of this tent while the Whip were playing. Everyone was jumping around me and I just sat on the floor, passing out and vomiting. It wasn’t great.

"But then the next day I woke in a ball pit and two people were having sex next to me. The sun was shining and they seemed very happy, so it was kind of the perfect ending. I quickly left, I might add – I didn’t want to disturb them."

When asked what her most "exhilarating" festival experience has been, Charli XCX added:

"At Bonnaroo festival a couple of years ago, we had nothing to do the next day, so we partied really really hard. My ex-boyfriend took acid with Billy Idol, which was quite funny. We all watched the xx, and it was the most beautiful moment ever and we were all crying. It was only about 10pm."
