Kevin Federline: My Children Come First
10/12/2006 AT 05:40 PM EDT
"Children come first," he tells Extra, in an interview scheduled to air Thursday.
Federline and his wife, Britney Spears, have two sons together: Sean Preston, 1, and Sutton Pierce, who was born on Sept. 12. Federline also has two other children – Kori, 4, and Kaleb, 2 – with actress Shar Jackson.
The aspiring rapper will release his debut album, Playing With Fire, on Halloween. Noting that he's not the first musician in the family, he calls Spears his musical mentor. "She gave me comments about the music," he says. "She's helped me on the business side of it."
And, Federline says, his wife's jaw "about dropped" when she heard the finished version of his album.
More immediately, though, Federline will appear on CSI: Crime Scene Investigation Thursday. On the episode, titled "Fannysmackin,'" he'll play a thuggish teen who hassles the investigators, hampering their work.
Following the release of Playing With Fire, Federline will test out his material in a series of live, club shows, beginning Nov. 4 in New York and running through a Nov. 12 stop in Norfolk, Va.
