Dr. Corbin Blue?

High School Musical 3 star Corbin Bleu turned his back on plans to become a doctor, so he could pursue his acting dream.

The 19-year-old hoped to specialise in paediatrics and even began preparing for a medicine degree while still at school - but he was forced to make a tough choice when fame and Disney came calling.

He says, "I love kids and really looking into the field in high school. I grew up loving math and science.

"But I had to make a choice."
