Emily Blunt's Favorite Part of Being a New Mom

Out of the millions of reasons why Emily Blunt loves being a first-time mom to daughter, Hazel, with her husband, actor John Krasinski, the "Edge of Tomorrow" star was able to narrow it down to just one.

"Bath time is kind of the best ever," Blunt, 31, said today on " Good Morning America." "They look like little Buddhas in there. You see the full kind of rolls of flesh, and it's great."

Blunt gave birth to Hazel in February but she and Krasinski, her husband of nearly four years, only showed their daughter to the world last month and through Twitter.

Krasinski tweeted a photo of the couple's daughter on May 13 as a way of introducing their daughter without a splashy magazine cover, something Blunt wholeheartedly endorsed.

"I do love that we were sort of in control of posting the picture of her because I don't like the idea of having a price tag on my child's head," Blunt said on "GMA." "So I just thought it would be better if we could control it."

The gentleness of taking care of a sweet newborn is a far cry from the film role Blunt is now promoting, an action-filled spot alongside Tom Cruise in the high-energy film "Edge of Tomorrow."

Though Blunt said she nearly broke her nose after she "smashed myself in the face with the butt of my own sword," the actress better known for roles in non-action movies such as "The Devil Wears Prada" still did nearly all of her own stunts in order to keep up with her co-star, Cruise.

"I definitely wanted to do all my stunts because he kind of does all of the stunts," Blunt said. "I didn't want him to be the only one showing off. I've got to do some of them."

"He is just so sweet and generous and such a pro at this stuff, and he was so emboldening and encouraging," she said of Cruise. "He is heavenly."
