The verbal slugfest between Grey's Anatomy'
s Katherine Heigl and the show's producers has entered a new round, with Heigl zinging her bosses for going public
on their salary dispute.
"I am embarrassed that this has become a public matter and disappointed that Touchstone felt it necessary to divulge private employment information," Heigl, 28, said in a statement Thursday.
"I had hoped I would be able to deal with this issue confidentially with my bosses. I dropped out of the renegotiation simply because I wanted to treat myself with the respect I was not getting from them."
fans will be happy to know that Heigl, who plays Izzie Stevens on the ABC hit, still loves her character. "No matter how unhappy I am about their decision to respond to this publicly, I continue to be passionate about and committed to this character," she said.
The actress dropped out of contract talks on Tuesday, a well-placed source told PEOPLE at the time, explaining: "Katie is disappointed and hurt that Touchstone doesn't value her as much as her other costars, especially Sandra Oh and Isaiah Washington."
In response, ABC Television said in a statement Wednesday that Heigl wasn't going anywhere: "We have a longterm contract to ensure she'll be with the show for several years to come."
The statement also said that producers had offered Heigl a significantly higher pay package and were "surprised" to see negative press coverage of their gesture.
