Allison Williams opens up about the one thing she'd leave 'Girls' for: Motherhood

Allison Williams has the career millions dream of starring in the popular TV show "Girls." So what would make her walk away from it all?

"My goal is to create a career I can walk away from and become a mom," Williams told Glamour magazine in an interview set to hit the stands Feb. 11. "I'd love to be a mom - and not have to bring my kids into my trailer. That's my long-term thinking," she said, according to the Daily Mail.

Although she said she would consider being a working mother, she says she would prefer not to.

"You gotta call it on the fly to a certain extent."

Born in 1988 in Connecticut, Williams played Deborah in "American Dreams," Kate Middleton in "Will & Kate: Before Happily Ever After" and Jillian in "The Mindy Project," landing her current role as Marnie Michaels in the New York City-based comedy in 2013.

The daughter of NBC Nightly News anchor Brian Williams, the 25-year-old actress is familiar with the burdens of being both a parent and someone in front of the camera.

She also interned for Tina Fey, a mother of two, while the comedian was working on the movie "Baby Mama."

"[Tina] is humble and efficient. That exact combination was everything to me. Tina knows everyone's name. It's funny, Lena Dunham is the same way," Williams said of the "Girls" creator and star. "It's hard to misbehave when your boss is so gracious."

When it comes to being a good friend, Williams said that while honesty is good, it's possible to have too much of it.

"I think the qualities I look for are loyalty, honesty and I think empathy is huge, because as a girl I am entitled to say often we think we want honesty but we want is for someone to say 'No, no you look great.'''
