"It's hard enough to be in a marriage, and then have a kid, then kids, it changes everything," bulky backup dancer K-Fed told People. "For me, I'd become more concerned with my children. Not that I ignored Britney, but my kids are always most important."

That's a noble sentiment, but another Star source claims, “Kevin acts like he’s the father of the year, but he’s far from it. Behind the scenes, he doesn’t have a job but still goes out of town to party for days and leaves his boys in the care of their nanny, Jenny. She’s amazing, but sometimes it’s a lot for her to handle."

Federline has claimed he's starting his own men's fashion line, Otzi. He also says he's working with a production company on an upcoming television project.

However, Star's snitch paints a picture of a far less-motivated Kevin Federline.

“Kevin loves smoking weed and spends hours getting high and playing video games with his buddies,” says the source. “He loves sexy hookers and regularly parties with them at his home in L.A.”

If these allegations are true, hopefully K-Fed will get his act together. With Sean and Jayden's mom jaunting around the globe to promote her hit album Circus, the boys need a sturdy father figure in their lives.
