It’s not all partying in Las Vegas for Britney Spears’s ex. Kevin Federline hit the party town to take in the Project fashion trade show hoping to gain some inspiration for a children’s clothing line he is planning on launching. “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,” he tells WWD. “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.” He does have a point. We hope to see Jayden James and Sean Preston trying out their daddy’s design soon.
