Turns out, Lindsay Lohan wasn't telling us the truth.

After RadarOnline.com was first to break the news that the troubled actress was involved in a hit-and-run in West Hollywood in September 2010 -- striking a nanny pushing a stroller carrying a child -- she denied it to us, telling us at the time, “I don’t know what you are talking about" -- despite the fact we'd already spoken to multiple eyewitnesses!

Now, the Mean Girls star might want to rethink her “I don’t know what you are talking about" defense, as we've learned that the nanny, Nubia Del Carmen Preza, filed a lawsuit with the Los Angeles Superior Court on Wednesday claiming injuries related to the incident. (Preza is also suing Black And White Car Rental, who provided LiLo with the Masserati Granturismo she was driving at the time.)

After a relatively drama-free 2012 so far, Lindsay Lohan could find herself back in court soon after a woman has filed a lawsuit against her in connection with a car crash, and RadarOnline.com has the legal documents with details of the accusation.

Nubia Del Carmen Preza was allegedly pushing a stroller across an intersection in West Hollywood in September 2010, when the Mean Girls star flew down the road in her Masserati and hit the nanny, catapulting the baby carrier into the air.
