I am taking this stance: there should be a line when it comes to paparazzi snapping pics of children.
Reese Witherspoon had a mini run in with some snappers this weekend while shopping with her children. She snapped back, instructing them to "back off". I've embraced the school of thinking that says, you can't get pissy if you are famous and people are taking pictures of you. You are famous, it shouldn't have come as a surprise that you'd be in the spotlight. Deal with it, or hang up your notoriety. But the women is with her kids. Give them a little space.
If photog's want to follow the starlet around trying to get photo proof of her elicit Jake Gyllenhaal affiar, I say happy hunting. Hypocritical or not, kids should be off limits.
