Kristen Bell is already a protective mommy. The House of Lies actress is expecting her first child with fiance Dax Shepard, and says she is super-mindful of everything she comes into contact with now that she's pregnant.

"I have been hyper-aware of everything . . . not only just in food," Bell, 32, told E! News. "I'm not strict, but I'm just very aware of what I'm putting in my body because it's affecting someone else. And that's kind of my responsibility. So, I'm working hard in the department."

And the mom-to-be, who is the face of Neutrogena Naturals acne line, is even being careful about what beauty products she uses.

"When you're pregnant your sensitivity to everything goes up," she explained, "so I'm working really hard at keeping everything I use very natural."

But other than that, Bell admitted, "I haven't really done anything yet."

"I think that because I'm still working on House of Lies, I'm still focusing on work while I'm in the earlier terms of my pregnancy," she said. "Once I get to the point where I'm going to want to be on the couch all day, I'll start looking through baby books and picking everything out."
