Yes that kid is a better actor than I'll ever be aged 10 or something, and yes that girl is a bigger music star than I'll ever be aged 8.
But Jesus!! Who forces their kids to become massive stars so young? They'll have drug habits and a fucked up sense of weird lost childhood forever. 1 and 3 child stars dies young, Will Smith has actively encouraged a 2 in 3 chance one of his kids is gonna have serious problems later in life. Good for a quick buck right now though right?
