Baby number 6!

Kevin Federline and his wife Victoria Prince welcomed a baby girl over the weekend.

The proud papa took to Instagram Sunday to announce the happy news. "Words cannot express the joy my children bring me," he captioned a photo of a festive "It's a Girl" flower arrangement. "We are very excited to welcome the newest member of our family. I love you with all my heart, @crownv_16."

The two have not shared other birth details, including their daughter's name, weight or measurements.

This is Kevin and Victoria's second child, but Federline's sixth overall. They already have 2-year-old daughter, Jordan. He has two kids with Britney Spears, Sean, 8, and Jayden, 7, as well as two kids with ex-girlfriend Shar Jackson, Kori, 11, and Kaleb, 9.

The lovebirds have been together since 2008, and they tied the knot last August in an intimate Las Vegas ceremony.

Congrats to the growing Federline family!
