Britain's Got Talent returns to our screens for a ninth series tomorrow. The auditions for the nationwide search for a Brit with very special talent will be televised for six weeks until a winner is chosen. But after the TV cameras subside, their show at the Royal Variety Performance is over, and they've spent their £250,000 - what happens to them? Scroll down for video .

From the incredible success of Paul Potts and Diversity to Attraction's questionable tactics and Jai McDowell's 'album flop', we look back at the show's winners to decide whether nabbing the prize on BGT can make you a star for longer than your 15 minutes. The biggest star to come out of the show by far is Scottish singing sensation Susa Boyle - but she didn't actually win. The reality show's judging panel - Simon Cowell, David Walliams, Amanda Holden and Alesha Dixon - have all said they are looking forward to finding fresh talent, and ITV chiefs are expecting bumper audience ratings. But is it really worth signing up? We look back at some of the biggest names to come out of the programme. Paul Potts . Series 1 - 2007 . Paul Potts performs on Britain's Got Talent in June 2007 .
