Katy Perry, Arctic Monkeys For The Brit Awards 2014
James Corden has also been confirmed to host the bash for the fifth and final time...
Speaking of her forthcoming stint on stage, the Unconditionally singer stated: "The Brits has always showcased the music that I love and am influenced by. It's an honour to play at such a prestigious event where musicality shines at its brightest."
Perry previously bagged the Best International Female award at the show in 2009, while The Monkeys have won five trophies since 2006 - including the Best British Album and Best British Group gongs in 2007 and 2008.
Corden will step down as Brit Awards host next year, but his involvement in the bash for the fifth time has made him the longest-serving presenter in the history of the ceremony.
The One Chance actor said: "I really love the Brits. I'm such a fan. I'll miss not doing it after this one but fully intend to enjoy every second of Brits 2014."
Hat designer to the stars and fashion icon Philip Treacy has also been announced to design next year's statue, revealing: "Music has always been my inspiration and I’m fortunate to have worked with some of the music industry’s greatest artists.
"My inspiration for the trophy comes from a uniquely British genre of music, Punk.”
Tickets for the show go on sale at 10am today, Thursday November 28.
The 34th Brit Awards will take place on February 19, 2014 at London's O2 Arena and will broadcast live on ITV.
