Jackson Brundage

We've been hooked on One Tree Hill since the beginning, but last year, when we heard the show would be fast-forwarding four years, we'll admit we were more than a bit skeptical. But once we laid our eyes on little Jackson Brundage, we were believers once more. Seriously, this whip smart kid has us in stitches every episode! Even co-star James Lafferty is a fan! "He knows everybody's name, from cast to crew to writers to producers," James tells us on his onscreen son. "He's incredibly smart. You can sit there and have a conversation with the kid like you would most adults, so it's pretty cool." With rave reviews like that, it's obvious there's more to come for Jackson.
