"My body is doing incredible things right now, and I'm not going to be ashamed of that," she said. "This time should feel celebratory. Because why should you be hiding your pregnancy?" she told Vogue magazine earlier this year.

"None of the dials are turned down," she said. "I think I even say yes to more now because I know it will be different on the other side of this. At first I expected some magical change, but really I remain who I am."

She also revealed that the pregnancy wasn't planned.

"Planning? I wouldn't say planning," she told Vogue about her upcoming motherhood. "But certainly not planning against it. I don't know when I ovulate or any of that type of [expletive]. We just had fun. And then it was just there on the test."

And what frightens her the most? "Postpartum depression. Will I feel out of control emotionally? Those are the stories I hear from other women that scare me."
