The mother-of-three will be making an appearance on QVC on 2 February to celebrate her special day with fans, who will be able to get their hands on the model's organic, vegan, zero sugar, and zero carb Prosecco.

Christie has been promoting the show since she left her Turks and Caicos holiday home last week and on Sunday, she delighted fans with a throwback clip showing her in her Italian vineyard trying out a bottle of her product, Bellissima Prosecco.

The clip shows the gorgeous 66-year-old sitting on a tractor wheel and dressed casually in a pair of denim dungarees, a blue shirt and a pair of wellies. Her hair can be seen perfectly tied into a ponytail with a red bandana, and she is wearing matching red lipstick and a pair of golden hoop earrings.

Fans were flawed by her video, with one writing: "You are so beautiful! When I was younger I had your big beauty book and would study it - and you were and still are such a beach babe!"

A second added: "The most beautiful woman that I have ever seen on a tractor!!! Happy Birthday Christie!!!"

Whilst Christie will treat fans to the best birthday show this week, she will no doubt also spend the day with her three children, Alexa, Sailor and Jack, who joined her in the Caribbean to ring in the New Year.
