Movie star Jennifer Garner revealed a certain moment in her husband's life that apparently made him happier than he's ever been.

What Did Ben Affleck Get Jennifer Garner For Valentine's Day?

On Wednesday, the actress made an appearance on The Tonight Show with Jimmy Fallon where she dished on the Superbowl that took place this year. As she and the talk show host enjoyed some green beer together, Garner mentioned how happy her husband Ben Affleck was when the Patriots tackled the Seahawks.

"There were tears," Garner admitted when Affleck watched the game. "Seriously, it was like the greatest moment of his life. It actually was, though. I birthed babies for him, and I still have never seen just the pure joy."

Does Ben Affleck Talk About 'Gossipy Female Things?'

The actress revealed that the game was pretty exciting for her as well since she was caught between what was going on at the Superbowl while putting her children to sleep. She jokingly said that she was giving her kids a lullaby while trying to see what was happening with the game.

"'Now I lay me down to sleep...goodbye!" Garner said with a laugh. "And that's motherhood!"

Fallon then asked the Alias star for advice about raising children since he has two daughters of his own. She mentioned that he should watch out for pinching and for any "clever" behavior when a new baby comes along. One of Garner's daughters apparently pretended to be a mermaid just so she could be held like a baby.
