The third series of British talent competition programme Britain's Got Talent was broadcast on ITV, from 11 April to 30 May 2009. The judging panel of Simon Cowell, Amanda Holden and Piers Morgan returned from the previous series; a fourth judge, Kelly Brook, was added, but removed from the series shortly after filming began. The third series was won by street dance troupe Diversity and finishing in first place and singer Susan Boyle finishing in second place. During its broadcast, the series averaged around 13.3 million viewers, with the figures partly helped by the notable performances of Boyle during her time in on the show, with her audition on the third series considered one of the most famous moments in the programme's history. The programme faced criticism during the third series for airing an unsuitable performance conducted in an audition, while Boyle's well-being became a major concern for producers following the final. Series overview Following open auditions held the previous year, the Judges' auditions took place across January and February 2009, within Manchester, Glasgow, Birmingham, London and Cardiff. Prior to the auditions, Kelly Brook was announced as a permanent fourth judge. However, after six days of filming the Manchester auditions Brook was removed from the series. She was credited as a guest judge when her appearance was broadcast. The third series proved popular amongst viewers for the performances of Susan Boyle, whom deemed her their favourite amongst the participants despite becoming the runner-up in the competition. Her performances made her internationally famous, launching her career as a singer, with her audition performance, involving her rendition of "I Dreamed a Dream" from the musical Les Misérables, being later posted to YouTube and earning around 100 million views within five days of its posting.
