Emily Blunt stopped by The Ellen DeGeneres Show and opened up about her 3-month-old daughter Hazel with husband John Krasinski.

When DeGeneres complimented her on how great she looks so soon after giving birth, Blunt said her secret to losing the baby weight was breast feeding.

"I managed to produce a lot of milk. I don't know why it helped me lose the weight," she said, E! Online reports. "It was be amazing if people who aren't pregnant could just breast-feed. I mean, it would serve everyone. It would help everyone out."

She also talked about how much milk she produced, saying “my boobs also thought I had 12 children.” She added, "I could have been the wet nurse in Medieval Times because I could have fed the village while they all went to work."

The Looper star went on to gush about her husband’s fathering skills, calling him the “greatest dad.” The actor shared the first photo of baby Hazel on Twitter on Tuesday.
