Last week, sources claimed that the former backing dancer and professional volleyball player Prince were looking forward to the birth of their first baby, after two years of dating.
Speaking to US Magazine, Federline confirmed that the pair are expecting a girl this summer.
He also revealed that they have chosen a name, explaining: "[Prince] 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."
Federline added: "We just found out the other day that we're having a girl. So it worked out!"
