Selma Blair isn't just Arthur Saint's mom- she's his conductor!
The Anger Management star and her son were spotted taking a mini train ride in El Lay on Monday.
Sure, it wasn't a real train, but it was a lot bigger than any of Saint's toys!
Ch-ch-check out the pics (below) to see the adorable pair taking the 3:10 to Cute-a!
Boy, that boy is getting big! He's on track to be taller than Mom in no time!
