Britney Spears to Have Another Baby With Kevin Federline?

Britney Spears is set to have another child with ex-husband Kevin Federline, according to a report.

American tabloid the National Enquirer claims that Spears, 26, is working on having another child with Federline -- which she hopes will be a girl.

A source is quoted by the publication as saying, "Britney has always wanted many kids, especially a daughter.

"And she'd like all her children to have the same dad -- Kevin -- so that they'll have the same DNA and a steady father figure.

"That's why she's been on such good behavior. She's trying to show Kevin she's healthy enough to become a new mom again."

Sources also say that Kevin -- with whom Britney has two sons, Sean Preston and Jayden James -- is so impressed with the former pop princess' recovery following her spectacular fall from grace earlier this year -- he's finding excuses to see her.

Kevin even dropped the kids off at the Toxic singer's Beverly Hills home for their scheduled visit on May 29, and the pair make regular phone calls to each other -- which reportedly turn into steamy phone sex sessions.

And in a bid to get her baby daddy back into her life full time, "Britney has given Kevin keys to her house along with a 'come over anytime, day or night' invitation," the source says. "They've even spent time alone in Brit's bedroom -- and they're not just playing cards!

"You can bet Britney and Kevin will be sleeping together, and the way they're acting, a pregnancy is definitely possible."

And although Britney loves her two young sons, "she is dying for a little girl. And she won't stop until she has one," says the source.
