With this year being the 10th anniversary of X-Factor, many are looking back on what the winners and losers have been up to since starring on the show and in case you haven't noticed, Leona Lewis is doing just fine.
The 28-year-old was working as a waitress at Pizza Hut when she auditioned for The X-Factor in 2006, and now it has been confirmed that she is the UK's biggest selling star from ITV reality show.
Lewis is reponsible for 4.4m of the show's 30 million singles sold and 3.9m of the 18 million albums sold.
