Former tennis champion Martina Navratilova is geared up for her trip to the jungle and says she won’t stand for it if she hears other campmates whining.

Martina says she is a very competitive person and will tell people exactly what she thinks of them and will get annoyed if they don’t listen.

She says: "Of course I’m competitive - nobody goes on the court saying I want to lose.

"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."

Martina says that she is joining I’m A Celebrity Get Me Out Of Here for a challenge and does hope to make friends and be a team player.

She says: "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. I love Sudoku."

Martina also confesses that she has never watched I’m A Celebrity-Get Me Out Of Here! and admits that she doesn’t really know what she is letting herself in for.

She says: "I’m flying very blind here. I have no idea what to expect other than having to rough it in the bush in Australia with nine strangers. So I don’t know what to expect. I’ve never seen the show and I don’t know if that’s good or bad. If I had seen it, if I would go, ‘Yeah, yeah, I really want to do that’ or if I’m like, ‘No way’. So I’m sort of going in on trusting in my ability to adjust, as Billy Jean King says, ‘Champions adjust’. So we’ll see if I can adjust.

"I am afraid of heights and being in a cave with no way out. I don’t know how many people don’t like spiders and snakes but I’m ok about it as I have spent a lot of time out in the bush so I should be ok about that."

m not too worried about it but the stuff that crawls. Not great. But I’m all right. Snakes, I’ve touched a snake. I was okay about that. We’ll see. Not great. Not horrible.”

The things Martina will miss most whilst in the jungle are her partner and reading the New York Times.
