Cheryl Cole was all smiles at the Olivier National Theatre in London on Monday night, where the ousted X Factor judge was celebrating her newest venture -- fabulous footwear!

To celebrate her partnership with U.K. fashion website, Stylistpick.com, the 28-year-old Brit showed off her amazing figure through the sexy cutouts in her scarlet mini dress. She styled her hair into a voluminous bouffant accessorized with a gold headband and sported smoky eye makeup.

The stylish star finished off her look with a pair of sparkling, sky-high heels. But despite their fabulous appearance, weren't such a walk in the park.

"Girls..Don't you just love taking your foot out of a heel and into your slippers..The best! Feels like my feet are having a cuddle.. X," the Girls Aloud singer tweeted after the event.

Cole's limited-edition footwear collection is due to hit stores in December just in time for the holiday season.

"Cheryl is the style icon and is amazingly warm -- a quality that has made her the nation's sweetheart," Stylistpick's CEO, Juliet Warkentin, said. "We believe that the launch will have a huge fashion impact, establishing fashion's greatest influencer as a major force in fashion design."

Cole will also curate her own picks on the site as well as give style tips to users.
