Pictures: Britain's Got Talent - where are they now?
After eight years of Britain's Got Talent, we take a look back at some of the memorable winners.
Dancing George Sampson won series two in 2008 after impressing viewers with his breakdancing. He has since appeared in blockbuster dance films and BBC teen drama Waterloo Road.
Diversity were the first dance troupe to win the show, back in 2009. They've enjoyed huge success performing on dozens of TV shows and even had their own dance tour.
The latest series was won by musical theatre boy band Collabro. The boys have an album on the way and will be going on tour in 2015.
Paul Potts won the first series of Britain's Got Talent back in 2007. The tenor singer from Bristol has released music and written a book which has been turned into a film based on his life.
Simon Cowell always wanted an animal act to win, and in 2012 he got his wish. Ashleigh and Pudsey have appeared on CBBC show Who Let The Dogs Out and now Pudsey is starring in his own film, voiced by David Walliams.
It wouldn't be a BGT gallery without Subo! Susan Boyle didn't even win the show, she was the runner up in 2009 when Diversity won. Despite that, she's topped the album chart in the UK and over in the US, and had her own headline tour.
Gymnastics group Spelbound won in 2010. Since then they've performed some shows and appeared in advertisements - but their line-up has been changed a number of times.
Singer Ronan Parke was the runner-up in 2011 when Scottish performer Jai McDowall won the show. Both of them had an album on Simon Cowell's record label - but both singers were dropped after poor sales.
