The nude photos, which appear to show the 21-year-old dancer and 'Waterloo Road' star in a number of explicit poses, are believed to have been leaked as part of the 'Snappening' hack of photosharing app, Snapchat.
George Sampson won 'Britain's Got Talent' in 2008
George, who won 'BGT' in 2008 with his 'Singing In The Rain' routine, is the fourth male celeb to have naked pictures circulated online.
At the weekend, nude photos of Kelly Brook's former fiancé David McIntosh appeared online. They followed the leak of private snaps of 'Doctor Who' star Matt Smith and Hulk Hogan's son, Nick.
Former 'Gladiator' David McIntosh took to Twitter after his nude shots began to circulate, tweeting: “So happy my naked ass brought joy to many boys & girls out der Im now gonna figure out a way to get more leaked, as my duty to humanity."
The news of George's leaked photos follows a mass celebrity hack which has so far seen naked images of stars including Jennifer Lawrence, Rihanna, Kate Upton, Kelly Brook and Kim Kardashian posted on file-sharing sites like 4Chan.
When ‘Hunger Games’ star Jennifer Lawrence's nude pictures were first circulated, they were accompanied by a list of over 100 celebrities thought to have also had their private photos accessed.
