"Preston's real outgoing. He seems to be a real daddy's boy too. He's very kind-hearted. I was that way when I was young. I feel like he's picked up that trait from me. But at the same time, he's a daredevil. Jayden is only two. He's coming into his character. He's a wild one!" Kevin Federline on his sons, Sean Preston, three and JAYDEN JAMES, two, with ex-wife Britney Spears.
