The news about the couple's new baby comes a month after the birth took place as the two have decided to remain incredibly private about their new bundle of joy. However, multiples sources have confirmed the news to Us Weekly.
According to a source, Norton and Robertson are "thrilled and excited for parenthood."
Norton got engaged to Robertson in 2011 after six years of dating. Us Weekly broke the new about the couple's pregnancy back in March.
