So the Heigl women's reputation was a hot topic at NBC's Televisions Critics Association press tour in Beverly Hills, California, on July 13 — in promotion of Katherine's new CIA drama, State of Affairs, for which Nancy serves as executive producer.
A reporter asked Katherine directly about the accusations — and after a lengthy pause, the 35-year-old responded.
"I can only say that I certainly don't see myself as being difficult. I would never intend to be difficult," she said, per Vulture. "I don't think my mother sees herself as difficult. It's important to everybody to conduct themselves professionally and respectfully and kindly. If I've ever disappointed somebody, it was never intentional."
Then Mama Heigl chimed in: "We have a partnership, we work in the business together. It just seemed like a progressive thing. I am her mother for sure, so of course I care about her interests, but I'm just learning about executive producing."
NBC prez Jennifer Salke gave her take, too: "Nancy's someone who has a strong opinion, but we've found her to be nothing but adamant to the process. Also, Katie really relies on her in her life. I would call her a momager, her best friend. She's a partner in her life."
Do you think that Katherine and Nancy are above reproach? Or do you think there's some diva behavior going on? Let us know in the comments below!
