Jenna Jameson just told our photog she plans on pressing charges against Tito Ortiz.
Fighting back tears, a clearly emotional Jenna was driving away from her home in Huntington Beach, CA moments ago -- when she stopped and told our photog, "I'm gonna be alright."
Jenna -- who was wearing giant sunglasses -- continued, "My babies are alright ... everything's OK .. he's in jail."
Jenna was accompanied by her father -- the man who we've learned made the initial call to 911.
UPDATE: Jenna just announced that she's quitting Twitter, saying "I cant take any more abuse from ANYONE.. To my sweet fans...thank you"
