Kevin Federline and girlfriend Victoria Prince have his fifth child

Kevin Federline becomes a father once again. The ex-husband of pop singer Britney Spears welcomed his fifth child last Monday, August 15 after his current girlfriend, former competitive volleyball player Victoria Prince, gave birth to their first daughter together at 6:33 P.M., 

Kevin and Victoria named their newborn Jordan Kay. The former backup dancer has hinted the name choice back in April. To Us Weekly, he shared, "[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 baby girl joined Kevin's expanding family. The 33-year-old, who once tried to be a rapper, has two children with ex-girlfriend Shar Jackson, a 9-year-old daughter Kori and a 7-year-old son Kaleb, and two more sons with ex-wife Britney, 5-year-old Sean Preston and 4-year-old Jayden.

Jordan Kay, who is Prince's first child, was born at 6:33 p.m. Monday. No word yet on Jordan's size or weight, but Federline already explained how he and his lady love settled on the baby's name.

"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," he told Us Weekly in April.

The rapper, 33, who now has more children than musical hits, was once married to Britney Spears and is the father of her two boys, Sean and Jayden. He also has two other kids -- Kori and Kaleb -- with ex-girlfriend Shar Jackson, an actress-singer who starred in "Moesha." Federline left Jackson to be with Spears. His marriage to Spears ended in 2007 in a very public divorce. Shar had no hard feelings, apparently: She and K-Fed appeared together in VH1's "Celebrity Fit Club: Boot Camp" in 2010.

Federline and Prince, 28, a former pro volleyball player, began dating in 2008. Now that the birth is out of the way, the couple could be hearing wedding bells.

"I do want to get married," he told the mag. "But I will wait until I have the courage to propose.
