The rumors spread like wildfire, but now, we can confirm that Britney Spears is in fact leaving Fox's X-Factor after earning a reported $15 million for her one and only season as a judge. "I've made the very difficult decision not to return for another season," Spears said in a statement today. "I had an incredible time doing the show and I love the other judges and I am so proud of my teens, but it's time for me to get back in the studio." We guess that's a good sign for fans of the femme fatale, but it still leaves a second seat open on the X-Factor season. After his team member Tate Stevens won this past season, Epic Records executive L.A. Reid announced that his run on the show had come to an end. No word on who Simon Cowell will recruit to fill their vacancies alongside Demi Lovato, but for Spears, this fall season is what inspired her to return to her musical roots. "Watching them all do their thing up on that stage every week made me miss performing so much," she exclaimed in today's statement. "I can't wait to get back out there and do what I love most."
