Can you tell that Emily Blunt gave birth three months ago?

Turns out, she has a pretty basic weight loss secret.

"I found breastfeeding to be the thing," Blunt told Ellen DeGeneres. "My boobs also thought I had 12 children... I found that because I managed to produce a lot of milk, I don't know why, it helped me lose the weight."

Blunt, 31, and her husband, actor John Krasinski, 34, welcomed their first child, daughter Hazel, in February. Now three months old, Hazel is "just stinkin' cute," Blunt gushed.

"I remember, we were in the recovery room afterward and this nurse came in... she said, 'Damn, your baby is so cute,'" she said with a laugh. "I went, 'Mabel, I think you say that to everyone and she went, 'No, I don't!' She went, 'When I know a baby is ugly, I say, 'You had a baby!'"

But the actress, who stars in the film "Edge of Tomorrow," alongside Tom Cruise, didn't only gush about her daughter. Krasinski, she said, is "the greatest dad" and "the burp king."

"He can get a beer burp out of this kid -- it even surprises her!" she said. "She loves him. Just loves him."
