|Kaminski/Splash News Online|
Rudds in red! Both sporting plaid button-downs, Jack Rudd, 4, holds tight to dad Paul‘s hair — ouch! — as they run around a beach boardwalk with pals on Sunday in California.
Jack is the first child for the actor, 39 and wife Julie Yaeger. Paul’s new movie, I Love You, Man, is in theaters now.
