NEW YORK —  Britney Spears dumped him and his debut album bombed, but Kevin Federline says he's doing "great."

"I am good, I am great, you know ... just moving along, progressing and taking it all in stride," the 28-year-old aspiring rapper tells "E! News" in an interview that was to air Wednesday night.

Spears, 25, filed for divorce last month after two years of marriage. She and Federline have a 1-year-old son, Sean Preston, and an infant son, Jayden James, who was born Sept. 12. Spears is seeking custody of both children, with visitation rights for Federline.

Federline, who is seeking spousal support and sole custody of his sons with Spears, says he's a family man and "that is the truth ... in all honesty, that is what it is."

He is also the father of a 4-year-old daughter, Kori, and a 2-year-old son, Kaleb, with actress Shar Jackson. They dated before he became involved with Spears.

Meanwhile, the media is giving the club-hopping Federline a tough time.

"I laugh a little bit about it you know," he said. "I don't take it too seriously. Those are people who don't really know who I am."

His debut album, "Playing With Fire," sold a dismal 6,500 copies in its first week of release. The CD was released Oct. 31.

When asked about it, Federline says he's "working it slowly, still trying to get out there and do more stuff ... I got a lot of options on the table right now."

His New Year's resolution?

To be "a little bit wiser, a little bit stronger."
