Chris Martin and Noel Gallagher will duet at the Brit Awards.

The Coldplay frontman looks set to join the High Flying Birds rocker on stage during his performance at the ceremony, which takes place on February 21 at London's O2 Arena.

BRITs host James Corden said during an interview on BBC Radio 2: "I think - and I don't know if this is true and I'm almost certain that I'm not supposed to tell you - that Chris Martin is going to accompany Noel on the piano."

Its shaping up to be a busy night for Chris, as Coldplay are also due to perform their duet with Rihanna, 'Princess of China'.

In addition, Ed Sheeran, Rihanna and Florence and the Machine will also perform at this year's BRITs, while Adele is expected to make her first UK public appearance since suffering a vocal cord haemorrhage in October.

Meanwhile, Blur's Damon Albarn and Graham Coxon are to join forces with Dry the River and Ed Sheeran at War Child's annual BRIT Awards show on February 19 to raise money for the organisation.

War Child Music Director, Ben Knowles, said: "War Child's annual BRIT Awards show has become a unique and important date in the music calendar.

"We believe music can make a difference, it can change lives. This year's amazing line-up will prove that - it will make for a stunning, unforgettable night and one that will raise money to help thousands of children affected by war."
