The Brit Awards are set to take place with a raucous evening expected as the biggest event in the British music calendar celebrates its 30th show.
Lily Allen, Lady Gaga, Pixie Lott and Florence And The Machine make it a battle of the babes after heading the shortlists with three nominations each.
But there will also be an array of eye-catching one-off performances at the show on Tuesday night - and even a royal endorsement - for the anniversary night at London's Earls Court.
Prince Harry has recorded a special message to be aired during the live show, praising the event as it takes place for the 30th time.
There will also be spectacular collaborations - for which the Brits has become increasingly known - including a showpiece duet between Florence Welch and Dizzee Rascal - both of whom are hot tips to win trophies.
Other performers include Kasabian, Lady Gaga and Jay-Z, who will take to the stage with Alicia Keys.
Lily Allen is set to play, as is Cheryl Cole, whose husband Ashley is at the centre of newspaper stories about texts allegedly sent from his mobile phone.
Comedian Peter Kay will host the event, which will see Robbie Williams rewarded for his outstanding contribution to music with an honorary award. Robbie will also round off the show with a live performance and is nominated in the best male category, against Calvin Harris, Dizzee Rascal, Mika and Paolo Nutini.
Lott, Allen and Welch go head-to-head in the best British female category, with Allen and Welch also up for best British album. Allen rounds off her nominations by competing for best British single with The Fear.
