The Man Up star confirmed that she and husband Scott Campbell are expanding their brood with another addition as she debuted her burgeoning bump in a clinging black dress at the AG + Vanity Fair Opening of Saved in Los Angeles on Thursday night (08Dec16).

Lake and Scott are already parents to two-year-old daughter Nova.

The 37-year-old actress is most well known for her work on screen but is also enjoying huge success as a writer, director and producer.

Speaking shortly after welcoming Nova into the world, Lake explained to The Frame that becoming a mother has definitely changed the way she works and her approach to her craft.

"Before my daughter, I definitely was a workaholic. And I still am, and that's a part of the texture of who I am, but I had no idea that I would consider my daughter in every breath that I take," she smiled. "That can be exhausting, certainly, and I understand that it's not even sustainable."

Lake added that balancing motherhood with her various professional pursuits takes a great deal of time. But if she didn't sleep, the actress joked she would have enough time for all her ventures.

"I consider making movies a great privilege, and I also wanted to start a family. So those two things came at the same time, and there are only so many hours in the day," she continued. "I often joke that women would do a lot better if we had clones of ourselves or we could exist in alternate realities simultaneously, or just not sleep. If I didn't sleep, that would really alleviate a lot of my problems, because I could just write through the night."
