Tito Ortiz Sued Over MMA Trash Talk

Tito Ortiz is on the receiving end of a serious legal attack -- one that started after the UFC legend bashed "Rampage" Jackson's former trainer to the media.

The guy filing the lawsuit is Juanito Ibarra -- a fighting expert who claims he's trained more than 15 world champs and several Olympic Gold Medal winners. Ibarra's pissed over an interview Tito gave to a website back in 2008, in which the fighter ripped Ibarra as a "thief" who had financially "taken advantage of Rampage."

In the lawsuit, filed today in L.A. County Superior Court, Ibarra claims Tito's statements are all false and "highly offensive" -- and things got worse when scores of sports websites began publishing follow-up stories, repeating Tito's comments.

Ibarra is suing Tito and all the blogs and publications that ran Tito's interview for defamation, invasion of privacy and emotional distress.
