The actress took to the microblogging site on Friday (22Apr11) to vent her rage following the alleged incident in the city, branding the hotel heiress "irresponsible" and the "worst driver ever".
She writes, "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**ch... Paris Hilton - horrible excuse for a human being... What an irresponsible person... What a lame existence... I wouldn't be as p**sed if I wasn't a mom."
Hilton hadn't responded to Shahi's comments as WENN went to press, simply writing on her Twitter page on Friday ,"What a beautiful day in LA today. I love this city!"
