Nikki Bella gave birth to her son, Matteo Chigvintsev, on July 31, less than one week before her due date. After keeping her little guy off of social media for a few weeks, the proud mom, along with her fiance, Artem Chigvintsev, finally debuted Matteo in a shoot for People magazine at the end of August.
