She is also known for her long blonde locks, but she clearly decided to change things up this week, as she proved on Instagram.
The mum-of-five shared a new selfie to the social media site which showed her in a car looking to the side. Instead of her usual blonde, her main was a beautiful light auburn.
She captioned the image with a reference to Frozen, writing: "Finally I can play Anna," adding a snowflake emoji.

Georgia shared a picture of her hair makeover
Earlier this month, Georgia caused a stir when she shared an empowering breastfeeding photo to Instagram.
She posted a sweet photo of herself feeding her youngest child, two-year-old daughter Birdie, and was soon met with a flurry of fan comments about the post. The 37-year-old mother was pictured sitting on the floor of her house, feeding her little girl, who was lying on her stomach.
The star is a doting mum-of-five
She wrote: "Keeping me grounded. #breastfeeding" Georgia's Instagram followers applauded her decision to normalise breastfeeding and to keep feeding for longer – as long as it still works for both mum and child.
One follower penned: "Right there with you, still going strong at 3 years old, who knows when he'll decide to stop."
Another commented: "This is so inspiring!". A third shared: "Fed both my womb gremlins until they were 5 and a half and it was simultaneously the best and most difficult thing I've ever done."
