Sarah Shahi was tweetin' mad over Paris Hilton's bad driving that the Fairly Legal star apparently observed.

"Paris Hilton — worst driver ever. Almost hit me, then ran a stop sign. What if there was a kid around that corner, you dumb b----," Shahi posted on her Twitter account Friday.

But that wasn't all Shahi had to say about Hilton. She also called the heiress a "horrible excuse for a human being," a "blonde piece of s--t" and described Hilton's existence as "lame."

Shahi, 31, further tweeted: "You're not an elitist just because you have money. You should apologize ... to humanity."

She qualified it all by saying, "I wouldn't be as pissed if I wasn't a mom."
