Since breaking up last year, reigning porn queen Jenna Jameson and Tito Ortiz's relationship has been anything but amicable. Now Jenna's escalating, claiming Tito beat her and routinely abused drugs.

A while back Jenna lost custody of her twin boys to Tito after a vicious custody battle, and now she wants to tell her side of the story ... in 140 character pieces.

Jenna went on a tweeting spree yesterday, May 30, accusing the retired MMA fighter of all sorts of dastardly deeds, including drug use and child neglect.


She then began posting pictures of Tito's alleged drug stashes, which she claims he used before fights. (There's also a diet A&W root beer in there, which does not taste as good as regular.)


And claimed he nearly killed her earlier in the year.


And so on, and so on.


After a day of this, Tito struck back, telling TMZ that Jenna's story is bogus.

"The unfortunate allegations being made against me are simply not true," Tito said. "I would never do anything to jeopardize my family. Being a great father and protecting the well-being of my children remains my top priority."

Curiously enough, Tito failed to address the drug photos Jenna posted. He was also busted on domestic battery in 2010, putting Jen in an arm bandage. And even a brass knuckle iPhone case wouldn't do much going up against Tito -- who weighs in at 6'2" and 206 lbs -- so there may be something to that.

Between Jenna and Amanda Bynes, Twitter is basically just a digital 'One Flew Over The Cuckoo's Nest' now. (Horse ebooks is totally Nurse Ratched.)
