Britney Spears is recording a new song for her sons.
The singer - who recently split from her fiance Jason Trawick and returned her $US90,000 engagement ring - is focusing on her children, Sean Preston, seven, and Jayden James, six, from her previous marriage to Kevin Federline to take her mind off the split.
The 31-year-old former The X Factor USA judge revealed her boys are her new inspiration on Facebook, saying: "I'm at the studio recording a new song for my boys. They are going to freak out when they hear it. So excited!"
Spears also hinted that she will be ready to release new music in the near future, writing: "It's a surprise so keep it shhhhh and don't be grouchy. I'll fill you all in soon ;)"
The Toxic hitmaker has thrown herself back into her work since splitting from her former agent Trawick earlier this month.
She is reportedly close to signing a five-year concert residency in Las Vegas worth $100 million per year.
But the city is notorious for its wild partying and her father Jamie Spears wants to make sure she doesn't get caught up in that lifestyle before he allows her to sign the deal.
A source previously said: "She has a bad track record there. This will be a bad temptation for her.
"They intend to set her up in a mansion in the Nevada suburbs. There will be bodyguards, her father, her manager - they will escort her to and from the show and watch her every move. They'll make it like her life in California, just hotter."
