Matthew Fox sued for assaulting bus driver

This is what you get when you punch a woman in the vajay! The female bus driver who Mathew Fox allegedly assaulted in August has sued him for $25,000, TMZ reports. She claims that when she punched Fox in the face (LOL) -- she injured her hand and fingers.

From TMZ:

The party bus driver who claims "Lost" star Matthew Fox punched her in the vagina during a stand-off last month has filed a lawsuit against the actor ... demanding more than $25k ... TMZ has learned.

In documents filed in Ohio, Heather Bormann claims a drunk Fox tried to board her party bus outside of a Cleveland bar on August 28 and demanded she drive him to the Ritz-Carlton Hotel.

Bormann explains that she "instinctively defended herself" -- and punched him in the face and head ... but she claims she injured her hand and fingers in the process.

Now, she wants more than $25k in damages for assault, battery and intentional infliction of emotional distress.
