Episode 1

First under the microscope is music mogul Simon Cowell, one of TV's highest-paid stars. As well as his successful music career, Simon's face has been a constant source of speculation. While he's freely admitted to overdoing the Botox in the past and is estimated to have spent upward of £50,000 on his teeth alone, just how much other work he's had done is still hotly debated. Queen of Pop Madonna is also put under close scrutiny. As one of the most widely recognised women in the world, Madonna's found a way to stay relevant over the past four decades by constantly reinventing herself. But in her push to stay young, the superstar's changing face has become just as much of a talking point as her music.
