Ahead of the nominations for the BRIT Awards later today (Jan. 18), performers at this year's ceremony have been unveiled.

The Feb. 16 event, organized by U.K. trade body the BPI, will feature performances from Lady Gaga, British pop act JLS and rock act Kasabian. It will be broadcast live on ITV1.

U.K. rapper Dizzee Rascal will perform a duet with alt-rock act Florence and the Machine, whose debut "Lungs" (Island/Universal) finally topped the U.K. chart last night (Jan. 17) after six months on sale. It moved 51,000 copies last week for total of 611,000, according to the Official Charts Company.

"It's an exciting line-up," said Ged Doherty, chairman of the BRITs Committee, in a statement. "These acts are young, vibrant and hugely talented. Each brings something different to the BRITs party. With Robbie Williams already confirmed and more surprises in store, BRITs-30 will be the music event of the year."

Robbie Williams, recipient of the outstanding contribution award, will close the show. Further acts performing at the show will be announced in the coming weeks.
