Kevin Federline is ready for a backlash over his brand-new role as white-boy rapper

"'He hates his children, he treats his wife like dirt, he gets high all day,'" he said, quoting his critics. "If I was that bad, you think anyone, let alone Britney, would put up with it?"

He has released his single "PopoZao" on his Web site. It got 2 million hits in eight days, he said, which proves there's interest.

He plans to release his debut album by this spring, but without featuring his wife on the album, said Federline, 27.

"We have collaborated," he said. "But I'm not going to put the songs on this album because it's like, 'Respect me first; then I'll show you what I've done with my wife.'"

Federline has two children with his former girlfriend, Shar Jackson. He and Spears had a son, Sean Preston, in September. They married in 2004.
