It was 2 days ago that we got confirmation on Nicole Richie's pregnancy [0], and we still aren't 100% sure about Christina, but we're already hearing the first rumors about the sex of both babies. InTouch [1] is reporting that Nicole and Joel will be welcoming a baby boy on December 30th, while Christina's baby girl is due on December 15th, according to a source at Cedars-Sinai Medical Center where both mothers-to-be supposedly had their sonograms. Now we know this is all total speculation, but you never know - remember how surprised we were [1] to hear that Nicole was pregnant in the first place? I am still digesting the news.
