Kevin Federline's a dad -- for the fifth time! 

Britney Spears' ex-hubby and his girlfriend, Victoria Prince, welcomed a baby girl Monday at 6:33 p.m., Us Weekly can confirm. The 33-year-old and his girlfriend of two years, 28, named their new addition Jordan Kay.

"Everything was perfect and everyone is doing well," Federline tells Us exclusively.

In April, Federline explained the name choice to Us: "[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." 

Federline and Spears, 29, share sons Sean Preston, 5, and Jayden, 4, who were "super excited" about becoming big brothers, according to their dad. He and ex-girlfriend Shar Jackson also have a daughter Kori, 9, and son Kaleb, 7.

Does Federline plan on making an honest woman out of Prince, a volleyball player turned special-education teacher? "I do want to get married," he told Us. "But I will wait until I have the courage to propose."
