Guests headed to the Mandarin Oriental Hotel to mark the Take That stars' wedding anniversary, and it was Cheryl and her co-star Kimberley who stole the limelight.
She topped it with an on-trend statement neckpiece by Malene Birger, available to buy at Net-a-Porter.com.
Kimberley, too, was glamorous in an all-glittering gold sequin mini, and arrived with her beau, Justin Scott.
Other guests who attended the bash included Denise Van Outen, Fearne Cotton, Ronan Keating and his wife Yvonne, Alesha Dixon, and, of course, Gary's bandmates Mark Owen and Howard Donald.
