Jason Donovan has warned budding stars "there's no degree in being famous".
The 'Too Many Broken Hearts' singer has urged up-and-coming talents to realise fame is not easy and doesn't last forever.
Jason, 40, said: "We all want to think we're going to turn into some sort of eternal moneymaking machine with incredible amounts of passion and inspiring people everyday but human beings don't function like that.
"There's a lot of kids that probably don't have that perspective and education. Knowledge is power and unfortunately there's no degree in being famous and selling ten million records."
Having seen the highs of fame in 1989 - when he had three UK number one singles and sold 1.5 million copies of his debut album 'Ten Good Reasons' - and the lows with years of drug problems in the late 90s, Jason is well qualified to give advice to budding stars.
He added: "Real talent will always shine through but life has ups and downs, its how you manage the long distance run which is one of the most important things.
"My advice would be to keep a sense of humour if you can, passion is always a good thing to have, keep fit physically - because that helps you in adversity and try and understand that it can all end, so therefore you should be grateful for what you've got when you get it."
