Britney Spears has confirmed that she will not be returning for the next season of The X Factor USA.

The 31-year-old singer has issued a statement announcing her departure, saying: "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."

Spears 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 star is currently working on a new studio album, the follow-up to 2011's Femme Fatale, with Jay-Z producer Hit-Boy.
