"If you want to hate me, cool, hate me," Federline, 28, says in an interview posted Thursday on People magazine's Web site. "You know why? Because all it's going to do is help me."
Federline, an aspiring rapper, has been aggressively promoting his debut album, "Playing With Fire," set for release Oct. 31. Amid a chorus of boos, he was body-slammed by wrestler John Cena in an Oct. 16 appearance on USA Network's "WWE Monday Night Raw." And don't forget his panned performance at this year's Teen Choice Awards.
"I know who I am," says Federline, who promises the album will show his "edgy side."
Last month, he portrayed an arrogant teen on CBS' "CSI: Crime Scene Investigation."
"I shocked myself," he tells People. "There were parts that I wish I would have done different, but there are parts that really took me, like, `Wow, did I do that?' I looked at myself and I was like, `It looked good. It looked perfect."'
Spears, 24, and Federline were married in September 2004. They have two sons, Sean Preston, 1, and a son born Sept. 12, whose name is reportedly Sutton Pierce or Jayden James. The couple have not confirmed the name.
Federline also has two children from a previous relationship.
"It's just time to get my stuff down while they're young, so I can sit back and watch them grow up," he says.
