In an interview with the Washington Post, Heigl explained that looking back at how she was described in her twenties "pisses me off." "I may have said a couple of things you didn't like, but then that escalated to 'she's ungrateful,' then that escalated to 'she's difficult,' and that escalated to 'she's unprofessional,'" the actress said. "What is your definition of difficult? Somebody with an opinion that you don't like? Now, I'm 42, and that s--- pisses me off." Her 27 Dresses costar, Marsden, told the Post that he always attributed her opinions to her "strength of character."

"But if you know Katie, it's simply because she has the courage to stand behind something she believes," he said. The Enchanted star went on to share that he always admired Heigl's "drive," and is not surprised that she's signed on to more executive roles. Heigl is both starring in and executively producing the upcoming new Netflix series Firefly Lane. "One element of Katie that I've always thought would define her was her drive," Marsden said.

"The more terrified and scared I was of doing something wrong, the more I came across like I had really done something horribly wrong," she said. Eventually this began to take a mental toll on Heigl, telling the Post that she she suffered from severe anxiety in the years that followed. "I asked my mom and my husband to find me somewhere to go that could help me because I felt like I would rather be dead," said Heigl. "I didn't realize how much anxiety I was living with until I got so bad that I had to really seek help. You can do a lot of inner soul work, but I'm a big fan of Zoloft."
