Who's That Girl, Justin???

As far as our celeb-loving eyes can tell, that girl seen with Justin Timberlake last night is neither Rihanna or Jessica Biel?
So who is she???
Whoever she is, she and Justin had a run-in with the paparazzi as they were leaving the Crown Bar nightclub in West Hollywood. When they were followed by several cars filled with photographers, Justin pulled over to confront them.
After causing quite a little scene, he took off again, but not before the photogs caught his lady friend holding two open beers in the back seat.
Very classy!
And where is all this rage coming from JT?
