The couple welcomed their first child in August 2012 via surrogate after multiple failed IVF attempts, and Giuliana's battle with breast cancer. "I used to say, 'Oh my God, I want four kids, five kids,' but gosh one is a lot . . . one's a lot of work," Giuliana told Us Weekly in March.

But they aren't ruling out the possibility of giving Duke a sibling. "We'd love to expand our family but as of now there's nothing in the works," Giuliana said. "I just want to make sure [I'm] giving enough attention . . . not spreading [myself] too thin. I just want to make sure I'm enjoying this time with him and not rushing anything."
