5. Kayla Collins
When it was announced that series 10 of I'm a Celebrity... would feature a former Playmate there were cheers from the male viewing public and Kayla Collins certainly didn't disappoint, spending most of her time in swimwear which left very little to the imagination. Each day Kayla played a game of Which is the Most Revealing Swimsuit I Can Wear Today? and boy did she pull some corkers out of her backpack. There were a selection of itsy-bitsy bikinis and a very revealing black swim suit. There were many costume changes and Kayla revealed prior to entering the jungle, "'I have a new swimwear line coming out in 2011 and I will be taking lots of my own outfits.'' It seems she was using the reality show as an opportunity to endorse her own products. Unfortunately, I'm a Celebrity... bosses were forced to cut some of the scenes which featured her in her own bikinis because they felt it went against their product placement laws. Her loss was the audiences gain and the daily dose of Miss Collins in her bikini was definitely the highlight of 2010!
