Britney Spears' ex-husband Kevin Federline just welcomed his second daughter with his wife Victoria (his sixth child overall) and last night, April 24, he took to Instagram to debut his new baby girl's first photo and reveal her name.

"We would like everyone to meet our newest Federline. Peyton Marie Federline. Born 4.4.14 8lbs 4oz.," Federline captioned the sweet photo of his newest bundle of joy, who is pictured cuddling with her big sis Jordan as her proud dad holds her tiny hands in his. Super sweet!

In addition to 2-year-old Jordan Kay, little miss Peyton Marie joins a big brood of older half-siblings: 7-year-old Jayden James and 8-year-old Sean Preston (Federline's kids with Spears), as well as 9-year-old Kaleb and 13-year-old Kori (Federline's children with his ex, Shar Jackson.)

Fortunately for the Federline family, it looks like all of the siblings have a great time together, as evidenced on Kevin and Victoria's Instagram accounts. The proud parents have posted happy snaps of all of the kids grinning from ear-to-ear and playing together, which is really nice to see. (Check out a pic of Jayden, Preston and Jordan all smiles below!)

It genuinely seems like family is the most important thing for Kevin Federline -- and he appears to be a great dad to all of his kids. Congratulations to him, Victoria and the entire Federline family on their newest bundle of joy!
