Britney Spears' sons are going to have a little sister! Late last week, the pop star's ex-husband, Kevin Federline, announced he was expecting a child with girlfriend, Victoria Prince. And Tuesday, he revealed they're having a little girl, UsMagazine.com reports.

Prince, a former professional volleyball player who oddly shares the same birthday as Spears, and Federline have been dating since late 2008. She is five months along and the couple plans to name their little girl Jordan.

"[Victoria] said that if we were going to have a little girl, she wanted to name her Jordan. And then, we actually thought that it was a boy, but we stuck with the name Jordan because, you know, it fits both ways," the daddy-to-be told UsMagazine. "We just found out the other day that we're having a girl. So it worked out!"

Jordan will be Federline's fifth child: He and Spears have sons Preston, 5, and Jayden, 4, and he and ex-girlfriend Shar Jackson have a daughter Kori, 8, and son Kaleb, 6.
