International pop sensation Britney Spears is thinking about retiring after she finishes her Las Vegas residency.

The 32-year-old singer, who has just released her eighth studio album Britney Jean, has revealed she might give up music after her two-year stint at Planet Hollywood and wants to expand her brood.

During an interview with Mario Lopez, she said: "I might [retire], who knows ... I may have two more kids and get married ... I'd like to have more kids."

Spears has been dating lawyer David Lucado for eight months after splitting from then fiancé Jason Trawick and has two sons with ex-husband Kevin Federline, Sean Preston, eight, and seven-year-old Jayden James.

The Extra host wanted to know if Britney wants girls or more boys, but the singer said "as long as they're healthy," she doesn't mind.

She added: "I think it does kind of help with dating someone not in the business, I could kinda understand if you're dating someone in the business they'd understand what you're going through every day and stuff.

"I feel like the chemistry kinda speaks for itself when you date someone out of the industry."

The singer begins her Las Vegas residency on December 27th.
