Carol Vorderman is "challenging" herself with 'I'm A Celebrity... Get Me Out Of Here'.
The 55-year-old star is looking forward to the adventure that the Australian jungle gives her, according to her best friend of 12 years Amanda Prowse.
Amanda said: "When she got into university, most girls didn't go to university. She's always worked in a male-dominated environment of engineering and maths, and had to push herself. She is hard as nails ...
"Flying has given her so much confidence. The fact she has conquered it has made her think, 'I can do anything.' Going into the jungle is in the same vein, it's adventurous and it's challenging herself to do something that gets your heart racing. She has always loved the show and the time is right. Her diary has always been chock-full before and now it's a case of, 'Why not?'"
Now Carol's children - Cameron, 19, and Katie, 25 - are older, she has the "freedom to follow her heart" and is "flying the flag" for women over 50 everywhere.
Amanda added: "For the first time in her life, her children are older and her time's more her own and that's given her the freedom to follow her heart. I've never known anyone work as hard as Carol has. She's such a professional and goes crazy working on the detail of whatever she's involved in.
"She's flying the flag for women over 50. If she's not dancing on tables in the early hours then she's out hiking around the world. I've got so much admiration for her. She's certainly not going to put her slippers on and start knitting."
And Amanda has assured fans that Carol will take on everything she is given on the ITV show as she is "very tough".
She added to The Sun newspaper: "Carol is so stunningly beautiful and very sexy. I think everyone finds her attractive but mainly because she's a nice person.
"She's the full package, she's warm, funny, kind and her best quality is she finds joy in other people's good fortune. She's going to do brilliantly because she's also very tough."
'I'm A Celebrity... Get Me Out Of Here' begins on Sunday November 13 on ITV.
