Last week the "Fairly Legal" star, Sarah Shahi took to Twitter.com to launch a scathing tirade at the hotel heiress over the alleged incident in Los Angeles.
Sarah Shahi wrote, "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."
But Hilton has now spoken out to slam the accusation, insisting Shahi has confused her with a doppelganger.
She tells Extra News, "I was so shocked when I read that. I wasn't even driving that day. I just came back from Vegas with my boyfriend - and we were home relaxing. I hadn't even been in the car that day."
"There are a lot of Paris Hilton lookalikes who do it for a living. They're always doing things and I'm getting blamed for it. So this could be another incident like that."
