Model and singer
Age: 24

Aja Rock certainly knows how to keep busy - juggling a full-time job, being mum to her gorgeous three-year-old son Brooklyn, modelling, television work... and recording her debut album.

Growing up as the eldest daughter of legendary music producer Bob Rock, Aja spent her childhood surrounded by the artists he worked with - including Metallica, Bon Jovi, Motley Crue, The Cult, Bryan Adams, Cher and David Bowie. So, following her own musical dreams has been the natural next step.

Aja is also an established lingerie and swimwear model, and has won numerous competitions. Since moving to New Zealand in 2003, she has featured on the cover of Ralph twice, and was listed by the magazine as one of the "200 Sexiest Women On The Planet".

For her second visit to Treasure Island the gorgeous blonde knew she would have to confront one of her biggest fears.

"I'm pretty terrified of spiders. I lived in Hawaii for 10 years and there were always cane spiders in the house and it was horrible! It would be great to overcome my fear of spiders doing this ... although it seems unrealistic."
