Cheryl Fernandez-Versini Puts Her Best Foot Forward At Ant And Dec's Star-Studded Birthday Party (PICS)

Cheryl Fernandez-Versini led the way at Ant and Dec’s joint 40th birthday party on Thursday night, putting her best foot forward in a cream dress, complete with thigh-high split.

The ‘X Factor’ judge was accompanied by her husband Jean-Bernard Fernandez-Versini at the swish bash, which was held at the Kensington Roof Gardens.

Cheryl’s had some trouble in the style stakes recently, and this ensemble is certainly a step up from her recent ‘X Factor’ audition outfits.

Ant and Dec celebrated the big 4-0 with a number of their famous pals, including Holly Willoughby, who ditched her demure ‘This Morning’ look for a racy low-cut number, complete with a daring, sheer panel.

While it's Ant's birthday next month, Dec celebrated his in September - but it's not exactly a surprise that they went for a joint party, is it?

Sorry to sound like grandmas, but we're glad Holly wisely brought a coat

Amanda Holden was also in attendance, sporting an LBD and gold heels.

The presenting duo reportedly pulled out all the stops for the bash, and even booked ‘80s band Black Lace’ to perform tracks including their not-quite-a-classic-but-definitely-a-wedding-disco-staple ‘Agadoo’.
