Here is my daily rant about Sienna Miller. Yes, I think she's beautiful, but she really needs to learn her celebrity ABCs:

A) Always be nice to the paparazzi, because if you cause a scene, flip them off or act like a diva, they're getting what they want - a money shot of you looking like an ass. Shots of celebs acting like lunatics command far higher prices than those of them smiling or acting normal.

B) Boinking married men is unacceptable, because everyone will find out, and you'll look like a total homewrecking ho, which no one likes. Yes there have been others before (Angelina, Rose McGowan, Clare Danes etc.) but they didn't act like they were guilty, and they certainly didn't pull this diva crap with photographers.

C) Cry and whine all you want, but people are still going to take your picture, and there is nothing you can do about it, so you might as well suck it up and smile. Besides, wouldn't you want magazine and blog readers to see you smiling or even expressionless instead of throwing a tantrum?

The other day, Sienna exhibited some very bizarre behavior while getting on an elevator with two friends. Check out the craziness below!
