Lady Gaga, Dizzee Rascal and Florence & The Machine will all be performing at this year's Brit Awards, it's been confirmed today.

Also joining the live line-up at the Earl's Court bash on February 16 are Kasabian, Cheryl Cole, former X Factor runners-up JLS and Robbie Williams, who will pick up his Outstanding Contribution To Music award at the ceremony.

Florence & The Machine and Dizzee Rascal's performance will see them duet together in a medley of 'You've Got The Love' and 'Dirtee Cash.'

Full nominations for next month's Brit Awards will be unveiled at London's IndigO2 tonight (January 18).

Alongside Robbie Williams, Ellie Goulding is the only other guaranteed winner with the Brits where she will pick up the Critics Choice Award.
