Where Do Babies Come From? The Movie 'Frozen,' Says Emily Blunt

Gives a whole new meaning to the song 'Let It Go.'

What happens when you combine Emily Blunt and "Frozen"? A baby is born -- apparently.

The actress told E! News that she thinks the mega-hit animated film might have helped her induce labor, as she watched it the night before she gave birth to her daughter, Hazel.

"There was nothing on and I was like, 'Do you think this will be good?,' and [my husband, John Krasinski,] indulged me and we went to see it," she explained of her last night out before motherhood. That gave quite a new meaning to the song "Let It Go," Blunt says. "I was like, 'I'm about to. I'm literally about to let it go.'"

Although Blunt wasn't cast in "Frozen," she's got a Disney movie all her own with "Into The Woods," which comes out on Christmas Day.

She may not play a princess, but any chance I get to see her sing and share the screen with Anna Kendrick is a-OK in my book. Blunt and Kendrick are just as fantastic a pairing as Anna and Elsa, right?
