article: 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 . Welsh opera singer Paul Potts, from Port Talbot, remains one of the most successful winners of Britain's Got Talent. The classical singer's post-show album One Chance sold millions of copies and was No.1 in nine countries. In 2013, James Corden played Paul in a Holywood movie about his life called One Chance. He is to perform during a short autumn tour at the Aberystwyth Arts Centre in North Wales on October 9 and Rhyl's Pavilion Theatre on October 14.

He ahs also appeared in the films StreetDance 3D and StreetDance 2. George Sampson performs a show-stopping dance on Britain's Got Talent in May 2008 .

Street dance group Diversity formed in 2007 and won the third series of Britain's Got Talent in 2009, beating bookies favourite Susan Boyle to the No.1 spot. In 2009 they toured with BGT, while 2010 saw the first dates to their Diversitoys tour sell out in 24 hours, and they've been touring every year since. There is currently eight members, from Leytonstone, Dagenham and Essex, which includes two sets of brothers. Ashley Banjo has become the standout star of the group, he is a member of the judging panel of Sky1's dancing talent show Got To Dance and has presented several other TV shows including Ashley Banjo's Secret Street Crew, with fellow members of the dance group. In early 2014, a new Sky 1 show called Ashley Banjo's Big Town Dance followed  saw Ashley and Diversity trying to bring the residents of Stockton-on-Tees tr together through dance. Perri Kiely has also had extensive solo success, winning the second series of Splash! and working as a UK presenter alongside Jordan Banjo.

In 2013 Jai performed at the March & Rally for Scottish Independence in Edinburgh, and in 2014 he was the support act on the Gareth Gates UK tour. Jai McDowall failed to set the music world alight after winning Britain's Got Talent in 2011 and was dropped by Syco records after his first album.

The pair also present the CBBC TV show Who Let the Dogs Out? In 2014, Pudsey starred in the film called Pudsey: The Movie, with his character voiced by David Walliams. For the last few years, they have also become a popular fixture on the pantomime circuit - this month they're playing Dorothy and Toto in the Easter pantomime of The Wizard of Oz at the Playhouse in Whitley Bay.
