Kylie Minogue and Gavin and Stacey stars James Corden and Mathew Horne will present this year's Brit awards, organisers said.
Among the stars appearing on the night will be Kings of Leon, Duffy and Girls Aloud.
Last week it was announced U2 will also be performing at the awards which are being held at London's Earls Court on February 18.
Chairman of The Brits Committee Ged Doherty said: "With performances from U2 and Pet Shop Boys already confirmed, the addition of Girls Aloud, Duffy and Kings Of Leon to the bill means we are heading towards a truly special Brits this year.
"Added to Kylie, Mathew and James hosting, it's going to be a must-see event. With the nominations launch taking place tomorrow night, the countdown to the 2009 Brits is now truly under way."
Radio 1 Chart Show DJ Fearne Cotton is hosting the nomination show at the Roundhouse in Camden, north London.
Among the acts tipped for success are Coldplay who released their fourth studio album, Viva la Vida or Death And All His Friends, this year.
Once the nominations for the 11 awards have been announced, pop fans can then vote for their favourite British single, live act and breakthrough act from the shortlists.
The best British single is finally decided on the night by a live telephone vote.
The Brits Academy, made up of 1,000 invited music industry insiders and critics, decide on the remaining eight awards. The Brit awards take place on February 18 and will be broadcast live on ITV1.
