Billie Eilish has announced an 81-date world tour starting later this year.

The What Was I Made For singer confirmed dates in North America, Australia and Europe from September.

Billie previously told music website Billboard her latest tour would be her most sustainable yet and she’s partnered with an environmental group to organise it.

Tickets for the tour – named after upcoming album Hit Me Hard And Soft – go on sale on 3 May.

Billie will start in Canada on 29 September before taking her show to the US in October.

She’ll then head to Australia in February, arriving in Europe next April.

The Oscar-winning singer has 12 UK dates, including two shows in Glasgow, six in London and four in Manchester.

Billie is a long-standing climate campaigner and she committed to making her last tour in 2022 “climate positive”, meaning it would eliminate more emissions than it produced.

She partnered with Reverb, a non-profit organisation that works to promote sustainability in the music industry, and will be working with them again on this tour.

Initiatives include reducing single-use plastics, offering plant-based food options and donating a portion of profits to funding climate projects.

In an interview earlier this month, Billie told Billboard she and her team were doing everything they could “to minimise waste in every aspect of my music”.

“My parents have always kept me well informed and hyper-aware that every choice we make and every action we take has an impact somewhere or on someone, good or bad, and that has always stuck with me,” she said.

“I can’t just ignore what I know and go about my business and career and not do something. That’s just not how I was raised, or how I want to live my life.”

For Hit Me Hard And Soft, which is set to be released on 17 May, Billie’s also announced plans to limit the impact of physical copies.

This includes making vinyl copies out of recycled vinyl with the packaging and album sleeves also made from recycled materials.

The singer has announced she would not be releasing any singles in advance, saying she wants fans to hear the album “in one go”.

The tour announcement came days after Billie revealed she’d followed in Lady Gaga’s footsteps and been added to the line-up of Fortnite Festival – the rhythm-based game within the popular online shooter.
