Britney Spears' ex-husband Kevin Federline sure knows how to reproduce! He and his wife Victoria just welcomed their second daughter (Federline's sixth child all together), he announced on Instagram.

"Words cannot express the joy my children bring me," the former reality star captioned the Instagram pic, which is of a bouquet of flowers in a tiny red wagon reading 'It's a Girl!'

"We are very excited to welcome the newest member of our family," Federline continued. "I love you with all my heart." He also hashtagged the photo, "#thefedz #sixthman I mean #sixthwoman."

In addition to their newest bundle of joy, Federline and Victoria are also the proud parents of two-year-old Jordan Kay. Of course, Federline is also the father of Sean Preston, 8, and Jayden James, 7, with Britney Spears -- as well as 13-year-old Kori and 9-year-old Kaleb with his ex Shar Jackson.

If Victoria's Instagram is anything to go by, it definitely looks like Federline is a man of his word: He does adore those kids. Her Instagram is filled with happy snaps of Dad spending time with his brood of kids, including Preston and Jayden. And it seems like the half-siblings get along as well, smiling broadly and goofing around in a series of photos. Check some of the snaps out below!
