X Factor winner Leon Jackson shows off dramatic transformation 18 years after victory

Leon Jackson, the winner of the fourth series of X Factor in 2007, has undergone a significant transformation since his victory. Now 35, he showcases a muscular physique and stubble, contrasting with his baby-faced appearance at 18. After being dropped by Simon Cowell's Syco label two years post-win, Jackson moved to Los Angeles. He shifted from formal attire to casual looks and began sharing fitness-focused images on social media. His winner's single, a cover of "When You Believe," was a commercial success, but subsequent releases did not perform as well. Jackson's career trajectory highlights the challenges faced by many reality show contestants.
