With contestants gathering down under for the ever-entertaining reality show, I have to say I'm delighted by the fascinating mix of celebs the producers have managed to put together. I'm already looking forward to seeing how they bond as a group - or not! - and cope with all those awful challenges.

I often wonder why celebs willingly put themselves through the show. The tasks are always so physically and emotionally demanding, and with the added pressure of being constantly filmed, I think I would crack! I certainly wouldn't like the cameras catching me on a bad day!

Take Esther Rantzen. With all the phobias she says she has, it really seems the poor woman doesn't stand a chance! But that said, I suspect it might be us who get the shock in the end. After all, the aim of the show is to make these high-profilers stronger by overcoming their fears and I think Esther might really surprise us!
