Adele is playing this year's Glastonbury. The singer announced the news herself while playing a show at London's O2 Arena on Friday night, March 18, telling the crowd in attendance that she's going to headline the festival on Saturday, June 25, AceShowbiz reports.

"Who's going to Glastonbury this year?" the "Hello" hitmaker asked the audience. "See you there. I'll be there. I'll be headlining on the Saturday night this year." She went on revealing that she was wanted to headline the fest last year, but "my record wasn't ready" at the time.

She also shared a message to anyone who might criticize the organizer's choice to book her. "And to the people who say I am too boring to headline, you're more f**king boring for moaning about me headlining," she added.

Glastonbury later confirmed Adele's upcoming appearance in a Twitter post. "As @Adele just announced live on stage in London, she will headline Saturday night at this year's Glastonbury Festival!" they wrote.

The fest's organizer Emily Eavis additionally shared her excitement to have the 27-year-old singer at the event. "What a great honor it is to have the wonderful Adele confirmed for this year's Saturday night headline spot!" she said.

Adele previously expressed her reluctance to perform at Glastonbury. "The crowds are too big - I don't know if I could do it," she said last year. She was convinced that the festival wasn't for her after watching Kanye West's set in 2015. "I went this year to watch Kanye [West] and I literally just crapped my pants on the size of the audience. It was pretty insane," she said.

This year's Glastonbury is scheduled to take place in Pilton, England, from June 22-26. The full line-up hasn't been unveiled yet, but it's been confirmed that Muse and Coldplay will headline on Friday and Saturday, respectively.
