The Chase's 'Governess' shocks fans with dramatic makeover transforming her into Ginger Spice!

We're used to only ever seeing her in a grey suit with her hair slicked back, but for a special celebrity Christmas episode Anne Hegerty (AKA The Governess) left fans shocked after she debuted a dramatic makeover which transformed her in Ginger Spice.

Going with a bolder look, Anne looks strikingly beautiful in the iconic blue Union Jack dress, with a matching red lippy and smokey eyes.

The Chase star also rocked a voluminous, ginger wig.

And her surprising new look - which was revealed in a teaser trailer - even appeared to leave host Bradley Walsh speechless ... well, for about two seconds until he quickly joked about her costume.

"Never mind Ginger Spice you look like a Ginger Nut," he can be heard saying in the clip.

Previously, Anne has revealed that she is not a fan of her uniform on The Chase.

"You can't imagine how much I dislike the suit," the 59-year-old said. "That is not what I would have chosen to wear."

She also confessed that she wasn't supposed to be called The Governess: "I was going to be called The Headmistress but then Bradley [Walsh] kept calling me The Governess.

We don't have any confirmation as to when the Christmas special is going to air in New Zealand, but we hope that it is soon!
