Now at just 19 years old she's conquered stadiums, the charts, and has millions of fans. Just this week, she was announced as the youngest ever act to headline Glastonbury Festival.
The tour announcement marks one of the biggest international concerts planned here since the pandemic disrupted the live music industry. And it's clear Eilish won't disappoint - she's known for her gutsy stage presence and incredible vocals.
Her latest album Happier Than Ever topped the album charts worldwide when it was released in July 2021, and features the singles Your Power, Therefore I Am, and NDA.
Fans will have to get in quick for tickets if her past shows are any indicator - her 2019 Spark Arena show sold out within minutes of going on sale. Her tour dates in the UK, North America, and Europe sold out in record time in May 2021.
The Herald's review of that show called it "a masterclass in well and truly making it".
Presales are on Monday, October 11 and Wednesday, October 13 and tickets go on sale to the general public on Friday, October 15.
