Billie Eilish Glasto's youngest headliner
US singing sensation Billie Eilish will make festival history when she takes to the famous Pyramid Stage in southwest England as the iconic Glastonbury's youngest-ever solo headliner.
The Grammy award-winning singer, 20, is scheduled to perform alongside her brother and co-writer Finneas O'Connell from 10.15pm on Friday local time (7.15am Saturday AEST).
The US pop star made her Glastonbury debut in 2019 when she performed on the Other Stage and treated crowds to a string of tracks such as Bad Guy and You Should See Me In A Crown.
In the weeks leading up to Glastonbury - one of the world's most highly regarded festivals - Eilish has played a string of UK and European tour dates and also hosted a climate event, Overheated, at London's O2 Arena.
She topped the bill at the equally high-profile Coachella in the US in April, bringing out guests Khalid and Damon Albarn for a set that thrilled fans and reviewers.
On the day Eilish headlines Glastonbury, Sir Paul McCartney will be warming up for his Saturday headline slot by performing at a nearby venue .
The surprise gig at the Cheese and Grain entertainment venue in Frome, Somerset, was announced on Thursday, with "first come first served" tickets selling out in less than an hour.
Sir Paul will become Glastonbury's oldest-ever solo headliner when he takes to the stage on Saturday.
The festival will see the former Beatle return to top the Pyramid Stage bill for the second time after a performance in 2004.
It marks exactly a week after celebrating his 80th birthday and 60 years of music making.
