Aside from her mind-boggling maths skills, the other thing Carol Vorderman is known for is being the queen of reinvention.
From her early days on Countdown in the eighties to her fondness for detoxing in the early noughties and now her fresh look in the jungle, Carol's image has changed more times than that of many Hollywood stars.
Let's take a look back over Carol through the ages as she takes on her latest conundrum in the jungle.
In this snap from 1994, Carol poses with a young cycle safety competition winner. This is still early in her TV career, well before the days of endless red carpets and hair transformations.
By 1997 Carol had added a few highlights and lightened up the fringe, but she was about to go for a more dramatic haircut...
With a new cropped do, Carol started to ramp up the glam factor by 1999.
And as we headed into a new millennium, Carol chose a new image in 2000 with these daring outfit choices as she became known for her incredible success with detox dieting.
By 2004, the maths whiz had upped her tan tone to fit with her blossoming celebrity status.
In this 2010 photo Carol can be seen embracing fashion and her curves.
Then came her first Rear of the Year win in 2011.
On a red carpet in 2012, Carol was beginning to look every inch the Hollywood star.
By 2013 the fringe was back, updated for a more modern look.
In this 2014 shot, Carol is trying her hand at some modelling for mail order shopping company Isme.
Later in 2014, Carol became the first woman to win Rear of the Year twice.
Last year she had ditched her dark tresses for a new blonde hairdo.
But Carol isn't all red carpet frocks and posing - this year she passed another pilot exam as she continued on her way to attempt to become the ninth woman in history to make a solo flight around the world.
Here's Carol just a couple of weeks before heading out to the Australian jungle...
And here she is on the launch episode of the series, not showing even a flicker of nerves at what might await her.
