Anne Hathaway on Her Adventures in Motherhood, ‘Alice Through the Looking Glass’

The Oscar winner portrays the White Queen in the new movie.

Hathaway revealed in an interview that aired today on “Good Morning America” that she has not seen the first 20 minutes of her new adventure fantasy movie, “Alice Through the Looking Glass,” because of her son, Jonathan Rosebanks Shulman.

“I'm sorry. I am a new mother and I didn't time the feeding schedule -- well, like I have any control over it,” Hathaway, 33, told ABC News’ Chris Connelly with a laugh. “My kid was hungry, I had to feed him, I missed the first 20 minutes so I can't tell you about the beginning of the movie.”

“Alice Through the Looking Glass” puts a new twist on the backstory of Hathaway’s character, the White Queen. Hathaway called that story her character’s “secret” in the movie.

“It was nice to find out that she wasn't so good all the time ...,” Hathaway said of her character. “She's covering something up. And that all that goodness is kind of put on so the people don't find out her secret.”

“I hadn't planned on ever confirming it and then I just, I had seen a photographer while I was on vacation, taking a photo, and I just thought, ‘It's such a joyful and a sacred experience, you know, carrying life,’” Hathaway explained. “And I just thought, ‘I don't want the first version of this to be out there with me covering or scowling at someone.'"

She added, “You know, that's not representative of the experience, so I chose a photo that I was happy with, and I put it out there.”

Hathaway's royal role in "Alice Through the Looking Glass" debuts 15 years after a crown was first placed on her head in the classic movie "The Princess Diaries."

“Alice Through the Looking Glass” is in theaters now.
