K-Fed and wife welcome 6th child

Sixth time's a charm!

Kevin Federline and wife Victoria Prince welcomed a new baby girl into their family on Sunday, making this child No. 6 for the former backup dancer.

"Words cannot express the joy my children bring me," he wrote on Instagram on April 6 along with a photo of a colorful flower arrangement in a tiny red wagon with the words "It's a Girl!"

"We are very excited to welcome the newest member of our family," he continued and tagged Prince. "I love you with all my heart, @crownv_16"

K-Fed is already the proud papa of sons Sean, 8, and Jayden, 7, with ex-wife Britney Spears. Before that he fathered two children with actress Shar Jackson — Kori, 11, and Kaleb, 9.

Aside from her half siblings, Prince and Federline's new baby will be the little sister to their oldest daughter, 2-year-old Jordan.

The couple was married in August in Las Vegas after five years of dating.
