The engagement so nice, they’re doing it twice. Ben Affleck was snapped browsing engagement rings at the Century City, Calif., Tiffany’s in the company of his mom, Sam, and son, Samuel, on Monday — presumably for his on-again love, Jennifer Lopez. You’ll remember that Affleck first popped the question to Lopez back in November 2002 during the Bennifer 1.0 days, using a 6.1-carat pink diamond by Harry Winston that reportedly cost $2.5 million. But the couple decided to postpone their planned 2003 wedding, blaming “excessive media attention” in a statement.
