Showbiz stars have been getting ready for tonight's Brits, the biggest night in the music calendar.
Sir Paul McCartney, Amy Winehouse, Kylie Minogue, Leona Lewis and Mark Ronson are performing at the Earls Court event.
Ex-Beatle Sir Paul, who will receive an Outstanding Contribution to Music Award, rehearsed his set yesterday. Take That are expected to seal their triumphant comeback with a gong after scooping four nominations.
Ozzy and Sharon Osbourne are hosting tonight's ceremony
X Factor winner Lewis and flamboyant singer-songwriter Mika are up for the same number of awards.
Arctic Monkeys, uber-producer and performer Ronson, Kaiser Chiefs and Kate Nash are up for three gongs each.
Rock royalty Sharon and Ozzy Osbourne will host the show live on ITV1 from their own on-stage "residence", described as part Addams Family mansion and part Beckingham Palace. The couple will sit on thrones surrounded by two giant sculptures of dogs and a totem pole featuring a skull and gigantic bat, a reminder of Ozzy's infamous bat-eating incident.
This year's Brits will feature a "glam" stage with gold drapes and a punk stage adorned with a ripped Union Jack. Doctor Who star David Tennant, actor Sir Ian McKellen, Gossip star Beth Ditto, and Bionic Woman Michelle Ryan are among the guest presenters.
Five times Grammy award-winner Winehouse is preparing to perform two numbers following her latest stay in rehab. One of the songs will be Valerie, as part of a medley with Ronson, Adele, and Daniel Merriweather.
But the star has only one nomination — for her cover of The Zutons' Valerie with Ronson — which is in the running for Best British Single.
Arctic Monkeys are up for Best British Group and Best British Album. Lewis will do battle for the Best British Female crown with Kate Nash, KT Tunstall, PJ Harvey and Bat for Lashes. With Girls Aloud up for Best British Group, Cheryl Cole is set to make her first public appearance on home soil since travelling to Thailand to consider the future of her marriage to errant husband Ashley Cole.
Minogue is to present ex-Beatle Sir Paul with his special award, before he performs a medley of hits at the ceremony which is expected to be broadcast with a 30-second time delay.
