Pop mogul Pete has compiled his years of expertise into book The Fame Factor.

Pete Waterman's career in the music industry has lasted an amazing five decades. He's sold 500 million records and achieved 22 No1s as one third of the record label Stock Aitken Waterman.

Now Pete has written The Fame Factor in which he gives advice to budding pop stars on how to make it big. Pete joins Holly and Phil to talk about fame, the rise and rise of Simon Cowell and his love of model railways.

In Pete's guide to making it big in the music industry he analyses ten of the biggest names in showbiz from Michael Jackson to Kylie to see what makes them so successful.

Each chapter features tips, advice and anecdotes, and information on how the music industry works. Pete says: "When I look at a new artist what I actually do is subconsciously apply a set of requirements and see how they measure up. Their resulting score is their fame factor."

Pete says that even though Simon Cowell isn't a pop star he embodies the determination you need to become successful. Pete first met Simon at his studios: "At the time Stock Aitken Waterman were the hottest producers on the block and Simon was a small time label manager looking for a hit record. Everytime I turned around he was there with another act, or a song, or an idea he thought would be a hit.” They are still mates and Pete went to Simon Cowell's 50th birthday party in October 2009.

Pete says the secret to success is working hard: "I'm up at 6am and if I haven't gone to bed until 2am then that's fabulous; the fuller the day the better."

When Pete first started out he put all of his money into his record company and had to sleep in his studio: "The receptionist got used to seeing me emerge from the basement into reception first thing in the morning with my towel and toothbrush."
