In late October 2010 -- after months of speculation -- Mariah finally revealed on "Today" that she and Nick were expecting. Less than two months later, Nick announced on his radio show that the couple were welcoming twins -- though Mariah had previously revealed the news to President Obama and first lady Michelle Obama when they questioned the singer about the status of her pregnancy while chatting backstage at the taping of TNT's "Christmas in Washington" special. (Fortunately, they're pretty good at keeping secrets!)
On April 30, 2011 -- their third wedding anniversary -- Nick and Mariah welcomed their son, Moroccan Scott, and daughter, Monroe. "My wife just gave me the most incredible anniversary gift ever in life! I won't ever be able to top this!" Nick tweeted.
