Holly Willoughby has dazzled fans as she dresses up for Christmas - albeit a little bit early.

This This Morning star rocked a festive red feathered dress in her latest Instagram post.

Holly, 39, captioned the snap of her twizzling in the sparkling number: "Filming something festive tonight... coming soon..."

To add to the Christmas vibes, she also added another photo to her Instagram Story with Mariah Carey's All I Want For Christmas playing alongside the post.

"Absolutely stunning," wrote one follower.

Another said: "You look so gorgeous."

"Wow what a dress. Love it," commented a third.

A fourth added: "The dress is amazing, you look gorgeous."

"Wow girl! You look amazing!!!" another said.

Others we're very intrigued about what Holly may be up to.

One said: "ooooooo i wonder what you're up to."

"Christmas strictly by any chance," quizzed another.

While other fans predicted it may have something to do with Celebrity Juice, the ITV2 panel show Holly quit earlier this year.
