Affleck and Lopez appeared to reunite in April when he was pictured at her LA home.

They were previously engaged between 2002 and 2004. Lopez once referred to the split from Affleck as “probably my first big heartbreak.”

The couple appears to be publicly enjoying their rekindled relationship with family and friends. They even brought their kids along for some recent escapades.

“They are slowly getting to know Ben,” a source recently told People. “Everything seems to be running smoothly. It’s very obvious that Jennifer is serious about Ben. She hasn’t looked this happy for a long time.”
