Actor Robert De Niro will soon become a grandfather — again. His son, real estate honcho Raphael De Niro, and Raphael’s wife, Claudine, will welcome their second child, a girl, in March, reports the New York Post. The couple also has a son, Nicholas, who is 18 months old. Raphael runs the DeNiro Group, a division of Prudential Douglas Elliman, where Claudine is also an executive VP. The pair met at the firm and were married in 2008 in the Bahamas.
