Call her fairly angry.
Sarah Shahi, 31, Tweeted up a profanity-laced storm after Paris Hilton, 30, apparently failed to watch the road.
“Worst driver ever,” Shahi writes. “Almost hit me, then ran a stop sign. What if there was a kid around the corner, you dumb b—-.”
But the Fairly Legal star did not stop there.
Calling Hilton a “blonde piece of sh–,” Shahi says in her Friday post she should “apologize to humanity.”
“Horrible excuse for a human being,” the former L Word star continues.
“I wouldn’t be as pissed if I weren’t a mom,” Shahi, who has son William Wolf Howey, almost 2, says. “What an irresponsible person. What a lame existence.”
A rep for Hilton did not immediately return a request for comment.
