Navratilova in the jungle 'to win'

Martina Navratilova has revealed that she is taking her competitive spirit into the I'm A Celebrity... jungle.

The former tennis champion said she is looking forward to the challenge and is hoping to go as far as possible on the show.

"Nobody that goes on this show says: 'Oh, I want to be out of there after the first week and just watch it you know from the hotel the rest of the time.' We all want to stay on," she said.

"I love new experiences and any time I have an opportunity to do something I've never done before I do it, other than bungee jumping. So I like new challenges, I like new problems."

Navratilova said she hopes her hand/eye coordination skills will stand her in good stead in the jungle, as well as her sense of humour and responsibility.

"I try to make people laugh and because, as a tennis player, as an athlete, I am a role model for a lot of kids. I always have in the back of my mind when I want to misbehave I'd better not do that in case it gets out. So you know you have that filter," she said.
