“L.A. Ink” star Kat Von D walked off the set of KTTV‘s “Good Day LA” this morning after host Jeff Michael alluded to her recent break-up with fellow tattoo enthusiast Jesse James.

Seconds before she was to appear on the show, Von D left the building after Michael mentioned the break-up in introducing a clip of “L.A. Ink” featuring James (which Von D had approved beforehand).

Von D’s abrupt exit left Michael and co-host Jillian Reynolds trying their best to explain to viewers what had just happened (video above).

“I think it was unprofessional on her part. I don’t know what she expected,” a “Good Day LA” producer told Radar Online today.

“Two days ago we got a message from her publicist that they did not want us to ask about Sandra Bullock or Michelle ‘Bombshell’ McGee,” the producer explained. “We agreed to that. If someone asks ahead of time, we decide ahead of time if we can do the interview and we agreed.”

For her part, Kat Von D tweeted, “Dear GoodDayLA, thanks for the waste of a perfectly good morning. Lack of compassion n respect for eachother never fails to dissapoint me.”
