Allison Williams would love to be a mother.

The 26-year-old actress is keen to set herself up with a career that she can balance equally with motherhood because she doesn't want to sacrifice precious time with her children for her job.

Speaking in the March issue of US Glamour magazine, she said: ''My goal is to create a career I can walk away from and become a mom. I'd love to be a mom -- and not have to bring my kids into my trailer . . . Or a balance [of both]. But you gotta call it on the fly to a certain extent.''

However, the 'Girls' star - who plays uptight Marnie Michaels in the hit HBO show - isn't ready to throw her acting career away for something more family-friendly just yet as she has a list of character she'd like to play first.

She said recently: ''I want to play a villain. I want to play a romantic heroine. I want to play someone who's on heroin. There's nothing I don't want to do. I want to play a guy at some point. I'll gain 100lbs, I'll cut my hair off, I'll do whatever. I'm not precious about any of it.''
