Ben has three kids with ex-wife Jennifer Garner – Violet, 16, Seraphina, 13, and Samuel, 10.
JLo adds: “It’s a beautiful outcome that this has happened in this way at this time in our lives where we can really appreciate and celebrate each other and respect each other.
“We always did, but we have even more of an appreciation because we know that life can take you in different directions.
"We have been in the game in the public eye long enough to know who we are as people and what really matters and what doesn't matter.
“We have kids and we respect each other.”
