Cheryl Fernandez-Versini led the style pack as she arrived at the Katie Piper Foundation party in a stunning strapless yellow and silver gown.
The star was all glamour in a form-fitting design from the Giorgio Armani Autumn/Winter 2014 collection, which she showed off to full effect by wearing her hair in a chic, slicked-back low-slung bun.
Her make up featured russet-brown smoky eyes and a pretty pink lip, and she completed her look with statement diamond earrings, a white envelope clutch bag, and silver stilettos.
Cheryl arrived at the event on the arm of her handsome French husband, Jean-Bernard Fernandez-Versini, who was suited and booted in black.
The couple got married in July at the exclusive Cotton House in Mustique after just three months of dating.
The singer was joined by her fellow X Factor stars at the bash, including Mel B, who opted for a strapless satin dress with peplum detailing, and was joined by her husband Stephen Belafonte.
Simon Cowell posed for pics with his partner Lauren Silverman, who was all elegance in an emerald-green number.
And Welsh television presenter Alex Jones opted for the most racy number of the night in a sheer slip covered in black lace.
Katie Piper set up her foundation to help burns survivors after she was the victim of a horrific attack back in 2008 when sulphuric acid was thrown in her face.
According to the Daily Mail, Katie spent seven weeks at the Chelsea and Westminster Hospital following the attack, before spending two years wearing a special plastic pressure mask for 23 hours a day.
She is now happy, healthy and works as a TV presenter while also recently becoming a first-time mum.
