Quinn made British music history as he was the youngest male solo artist and the first person ever, to have a number one album without releasing a single.
During the summer of that year, he was a judge on the ITV dance competition show Baby Ballroom, alongside Bonnie Langford and Pierre Dulaine.
On 22 March 2009, he and Filippov won the competition over Donal Mac Intyre and Jessica Taylor.
From 11 May to 28 November that year, he played Danny Zuko in the West End production of Grease at Picadilly Theatre.
Quinn was placed in the 16-24s category, with Simon Cowell as his mentor.
