Britney Spears' family New Year

Britney Spears is forfeiting a night out on New Year's Eve to look after her children.

The pop star is set to stay home on December 31 with sons Sean Preston, three, and Jayden James, two, while their father Kevin Federline - who has sole custody of the children - parties with new girlfriend Victoria Prince in Las Vegas.

A source close to Britney and her ex-husband Kevin told Britain's Daily Star newspaper: "Kevin has been getting on much better with Britney recently, so he didn't want to risk setting their relationship back by mentioning Victoria.

"And he knows she's desperate to see the boys over Christmas, so he's letting her visit them at his home over the festive period.

"He then added she could have them on New Year's Eve, as if it was a great favour."

It was recently revealed that the 27-year-old singer - who is currently enjoying a successful career comeback following the release of her new album 'Circus' - has asked Kevin to rekindle their relationship and move back in with her.

However, Kevin is apparently not interested in giving their romance a second chance.

He said recently: "There were times when I was up and down about it, but I just figure I've made all the right decisions."
