The Scream & Shout singer has now issued a statement announcing her departure, where she explained: "I've made the very difficult decision not to return for another season.
"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."
Britney added: "Watching them all do their thing up on that stage every week made me miss performing so much! I can't wait to get back out there and do what I love most."
The pop princess went on to add that Fox had already been told of her decision to quit.
Seeing as Spears will now have a lot more free time on her hands after stepping down from the XF USA panel, TMZ has claimed that the 30-year old is now 'in talks' with a major hotel in Las Vegas about having her very own residency in Sin City.
An insider revealed: "Britney has one very real proposal on the table, but now that it’s definite she’s leaving X Factor with a Las Vegas show finally in her future, it’s likely there will be a bidding war by other properties on and just off the Strip.”
