"Everyone is shocked," she told the magazine. "I mean, even we were completely speechless, and every time I shared the news with someone, I said, 'OK, are you sitting down?' And then I said, 'Feel free to say 'holy s--t' or congratulations because both are fine.' Because that's pretty much how I've been the whole time!"

"There are going to be some permanent birth control decisions made immediately after birth," she added.
