Sources close to TLC  ‘reality show’ LA INK are saying that Kat Von D went ballistic on producers earlier this week when she viewed screeners for upcoming episodes of the show — even threatening a legal war over several scenes that feature Kat trash-talking her on-again / off-again boyfriend Nikki Sixx (of Motley Crue).

The reason there is this little situation is that the footage was shot a while ago, while Kat found herself in the welcome arms of world famous ‘chopper builder/cheater’ Jesse James…and back then, she still harbored some ill-feelings toward Nikki.

But now, Kat and Nikki are back together — and when Kat previewed the footage from the upcoming episodes, which contained the anti-Nikki rants, Kat “freaked out.” (No shit…she realizes what a bitch she looks like!)

Kat demanded producers re-edit the show ASAP — removing all negative Nikki references and killing a storyline involving a “Nikki vs. Jesse” theme…or else she would file legal papers in an attempt to stop the show dead in its tracks. (Lawsuits seem to settle everything).

In the end — producers begrudgingly obliged, and Kat’s comments will never see the light of day.

Treez: I watch this show off and on. I think Kat Von D is kind of a bitch. I first thought this of the way she was shown in dealing with tattoo God Corey Miller. Nikki Sixx really comes off, on the show that is, as a pretty cool and humble guy. He really seems to be into Kat. Even putting up with that ‘Rooftop’ schmuck who is Kat’s f’n ROOMATE?!?!? So they break up, and she shows her shallowness talking that shit about Nikki ON CAMERA, which she knew they were always taping. So now that they are back together, she wants to clam up. Well, man up bitch. You talked that shit and Nikki should know. As a matter of fact, I’m gonna twitter the link to this story to Nikki and see what he has to say….Over and Out!! Crue 4 Eva!!!
