Heather Bormann launched a legal battle against the actor last year (Aug11), claiming he assaulted her while trying to board a party bus in Cleveland, Ohio after she informed him he was not on the private guest list.
The alleged victim was seeking more than $25,000 (GBP15,625) in damages for assault, battery and intentional infliction of emotional distress, but she has abruptly dropped the case.
Fox previously denied the allegations and filed a countersuit against Bormann for defamation. He has now withdrawn the papers, according to TMZ.com.
The actor was never formally charged.
Ironically, the news comes just days after his former Lost co-star Dominic Monaghan took aim at Fox on Twitter.com, revealing he is not friends with the actor because he "beats women".
