'Office Space' and 'Sex & the City' star is suing over a Wikipedia post that claims he is gay.

U.S. actor Ron Livingston is suing Wikipedia, saying the online encyclopedia's page about him incorrectly identifies him as gay.

The 42-year-old actor, best known for his lead role in the movie "Office Space," filed a Los Angeles County Superior Court lawsuit accusing Wikipedia of libel, invasion of privacy and for using his name and likeness without his permission, TMZ.com reported Saturday.

Livingston, who is seeking unspecified damages, alleges an unknown individual continues to alter the actor's Wikipedia page so the page claims Livingston is in a relationship with a man named Lee Dennison.

Livingston, who married Rosemarie DeWitt last month, says such postings are false.

The actor, who also started in the miniseries "Band of Brothers," and the movies "The Cooler" and "Adaptation," said once the offending postings are removed, the unidentified individual immediately replaces them.

TMZ.com said Livingston also alleges the same individual created pages on Facebook under his name as well as Dennison's. Both profiles on the social networking
Web site reportedly claim the two men are "in a relationship" with one another.
