Britney Spears' ex and the father of her kids, Kevin Federline has attended the Project trade show in Las Vegas on Tuesday hoping to get some new ideas for the kids clothing line he wants to market.

Being the dad of four, Federline may think he has the necessary baggage for designing clothes for children, affordable and fashionable in the same time. Like he would ever buy a pair of pants from his own money when Spears is giving him $20,000 a month as custody payments.

He tells WomensWearDaily.com,

"I'm trying to take it seriously and make a quality product for kids but not have parents pay like $500 or something ridiculous for a pair of jeans. You buy your kids a pair of True Religions then they roll around in the dirt like kids do and a $200 pair of jeans is gone. With this economy, I'm looking to do something much more reasonable".
