Emily Blunt and John Krasinski

Emily Blunt thinks her husband John Krasinski is "the greatest dad."

The 31-year-old actress, who gave birth to her first child, Hazel, with the 'Monsters University' star in February, says he has developed a very close bond with their daughter.

The 'Edge of Tomorrow' star told 'The Ellen DeGeneres Show' on Wednesday (14.05.14): "He is the greatest dad. She loves him, just loves him."

Emily is also absolutely besotted with their baby girl.

She said: "She's just stinking cute. Yeah, she's so cute. She came out like ready for a photo shoot. She was like... just perfect."

The British beauty, who tied the knot with John in Italy in July 2010, admits it took them a long time to find a name for the baby.

She said: "I find it very stressful naming a human being."

They eventually decided on Hazel after John found the name because "we both really like old lady names."

Meanwhile, Emily credits breast-feeding for helping her to lose weight after giving birth.

She said: "No, I don't know if other mothers had this, but I have found breastfeeding to be the thing [to lose weight]. 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."

She jokingly added: "I could have been the wet nurse in medieval times because I could have fed the village while they all went to work," adding that her breasts were like "two enormous heads."

John, 34, released the first picture of their three-month-old daughter on Twitter on Tuesday (13.05.14).
