"So, we got to the conversation about having kids and where we stood with all of that very quickly."

"It's something that I wanted for so long, that when I found out that I was actually pregnant, I was really surprised, in a good way of course," she said on "HillsCast" podcast when speaking about her first pregnancy. She also said that it "took me a while to really absorb it. I'm just really excited. I've been really lucky -- I haven't had sickness or anything like that."
