5 Seconds Of Summer, Snoop Dogg and headliners Muse and Foo Fighters are among the acts that have been added to the line-up for this year's Radio 1's Big Weekend.
The music event, set to take place at Earlham Park in Norwich, will see Florence And The Machine, 5SOS, David Guetta, Ben Howard, The Vaccines, Fall Out Boy and Charli XCX, performing on the Main Stage on Saturday 23 May.
Hip hop legend Snoop Dogg will be heading up the In New Music We Trust stage with British acts Rudimental, Ella Eyre, Years & Years and Jess Glynne, also performing.
Other acts confirmed for the stage include Hozier, Slaves, Mallory Knox and Circa Waves.
Confirming the band's headline slot, Muse frontman Matt Bellamy said: "I'm very excited to play. The last time we played Big Weekend, for us it was a disaster, so I can't wait to make up for it on this performance.
"I'm really looking forward to coming back and doing a great show. I'm pretty sure that we may unveil another new song that we will play for the first time which is pretty exciting."
Foo Fighters frontman Dave Grohl added: "I'm really excited - I can't wait to come out. I don't really think we've ever played there before so I'm looking forward to it."
With Grohl and co headlining the Main Stage, other artists entertaining audiences on Sunday 24 May will be Taylor Swift, Sam Smith, Rita Ora, Clean Bandit, George Ezra, Olly Murs and Imagine Dragons.
Jess Glynne, who scored her first solo number one earlier this month with single Hold My Hand, said of her upcoming performance: "My first Big Weekend in my own right and what a line up to be a part of. I can't wait to play Norwich with my band and let you hear some of the songs from my new album. It's going to be big."
In March, the 50,000 free tickets released for the music bonanza shifted in less than an hour. Most of the tickets were given to residents living in the Norwich area.
Those who were lucky enough to grab tickets and others who weren't, have given the eclectic line-up a warm response on Twitter:
