Katherine Heigl will return to television this fall in NBC's new political drama State of Affairs as a CIA analyst named Charlie Tucker. The new gig comes four years after the actress famously left her role as Dr. Izzie Stevens on Grey's Anatomy. In a new interview, the 35-year-old opened up about her decision to move on from the successful ABC show and spoke on the negative rumors regarding her reputation.

"I made a difficult decision, but it was the right decision for me at the time," Heigl told TVGuide.com about Grey's Anatomy. "I really just wanted to spend more time with my family and my new baby and extend my family and I'm really grateful to have been able to do that and I'm very grateful for these last couple of years."

As for the ongoing rumors that she and her mother/manager, Nancy, are hard to work with, the 27 Dresses actress insisted it's not the case.

"I can only say that I certainly don't see myself as being difficult," she said. "I would never intend to be difficult. I don't think my mother sees herself as being difficult. It's important for everybody to conduct themselves professionally and respectfully and kindly. So if I have ever disappointed somebody, it was never intentional."

The mother of two is now focused on her new role, which she called "an extraordinary opportunity." State of Affairs, executive produced by Heigl's mother, premieres this fall.
