After wearing head-to-toe black for the first 2 weeks of the X Factor live shows, Cheryl Cole gave us two non-black looks this weekend.

On Sunday night she dazzled in a sexy Kristian Aadnevik Spring 2011 mini dress straight off the runway from London Fashion Week.

The one-sleeve white mini dress with the silver stripes was more like the young, fun sexy Cheryl we’re used to seeing.

She completed her look with Nicholas Kirkwood black strappy heels.

I would’ve preferred the runway heels or heels in a similar colour, but I’m glad to see her sparkle back.

The judge/singer also performed her new single “Promise This” live on the show, which is the first track off her new album, “Messy Little Raindrops”.
