Jeff Goldblum and Emilie Livingston recently announced the birth of their second child. The couple took to Instagram Friday to welcome their newest addition while captioning the photo, "I can't believe it's been a week already!" she wrote. "River Joe Goldblum was born 4/7/17 at 8:53am. Charlie Ocean is such a sweet and caring older brother." The mother of two then shared a trio of photos, two of which included Goldblum.
