Because she wore this Atlanta PD hat to LAX yesterday. LOL at this PR move, which somehow simultaneously comes off as Reese apologizing, poking fun at herself, and giving the Atlanta 'po a delicate middle finger. Note the smirky little half-smile.
Still, hats off (HA) to Reese for putting something new out there for all us gossip-hungry Internet people to speculate about instead of this incredibly embarrassing (c'mon, Witherspoon, we legitimately thought you were better than that) police dashboard camera footage that trolliest of celebrity gossip trolls TMZ put on the web last week. Hey, everyone gets lousy drunk and yells at strangers about how Very Important they are from time to time, but most people aren't A-list celebs with previously squeaky-clean public reps. Lesson learned, Reesey.
