Heigl was on the KTLA Morning News Thursday to discuss her new flick, "Life As We Know It."
During the interview, anchor Sam Rubin asked the actress about a profile in Sunday's New York Times.
In the article, Heigl is accused of being far too honest for the Hollywood machine.
"Yeah, I think that was fair," Katherine agreed with the article's assessment that she hasn't been her own best spokeswoman.
"It's something I've spent a lot of time in the last year or so really thinking about or really trying to figure out, because, obviously, my career is important to me, and I'm really passionate about trying to keep it."
"I don't want to be the person digging my own grave or put myself out there in any way that would sort of hinder this great thing I've got going," Heigl said.
Heigl admits she is very "grateful."
"I've spent a lot of time trying to figure out where I kind of went off track and how and why and what I can do in the future to avoid that.
"The reality is, as he says in that article, nothing I said was particularly scandalous. It just had a tone," Heigl said.
"That's the most important thing I've learned as I get older... I can let go of the tone.
"I'll say what I gotta say and be honest, but maybe not so edgy."
