Details magazine has put Kevin Federline on the list of “50 Most Influential Men Under 45.” In fact, the father of four ranked #7.

Britney’s ex says, “To be a father is…everything. It shows me how little I am.”

Kevin, 29, who has two children with ex Shar Jackson and two with Britney, adds, “My TVs are pretty much G-rated right now. Anything from ‘SpongeBob’ to ‘Finding Nemo,’ and you know, I’m still trying to decide which one I like more.”

The rapper says he’s also focusing on an acting career, but insists, “I’d actually like to play somebody other than a bad guy or an ass.”
