Tickets to Billie’s Happier Than Ever tour, which is an all-ages event, go on sale on October 15, with pre-sales starting on October 11.

Meanwhile, last week she delighted fans by announcing she would be the youngest ever performer to headline at prestigious music event, Glastonbury festival.

The Lost Cause star teased fans by sharing a selfie on her Instagram Story sporting a Glastonbury festival hoodie with Glastonbury Festival, Worthy Farm emblazoned across it.

Billie then sparked major speculation she is performing at the world-famous music extravaganza in Somerset, South West England next year, with the caption: ‘2022.’

And on Monday, Glastonbury organisers Emily and Michael Eavis have officially confirmed the Grammy-winner will take to the Pyramid Stage on Friday, June 24, 2022, and Billie is set to make history as the ‘youngest-ever solo headliner’, while it’s also her first ever UK headline slot at a festival.

A statement on the official Glastonbury Twitter page read: ‘We are very excited to confirm that @billieeilish will headline the Pyramid Stage on the Friday night at Glastonbury 2022, to become the Festival’s youngest ever solo headliner. This will be her first UK festival headline performance.’

The Bad Guy chanteuse recently confessed she had ‘no idea’ Glastonbury was ‘even a thing’ until after she played the festival.

The superstar – who grew up in Los Angeles – played The Other Stage in 2019, and admitted she wasn’t aware just how big a deal it was to play the legendary festival when she got the invite.

She said: ‘I feel so embarrassed because I had no idea Glastonbury was even a thing. I was like, ‘What’s that?’

‘I didn’t know it was a big deal until after I played it. Everyone was like ‘oh my God, you played Glastonbury’ and I was like ‘Yeah, so?’ And then I realised. I am a little uncultured baby.
