Actress Emily Blunt says she had watched "Frozen" less than 24 hours before she delivered her daughter Hazel.

The 31-year-old had Hazel, now 10 months old, with husband John Krasinski.

`I saw 'Frozen' the day before I had my daughter. Isn't that crazy? There was nothing on and I was like, 'Do you think this will be good?', and John indulged me and we went to see it,` eonline.com quoted Blunt as saying.

Discussing the film's theme song `Let it go`, Blunt said: `I was like, 'I'm about to. I'm literally about to let it go.'`

Blunt shot `Into the Woods` while she was pregnant and says filming came at the perfect time for her.

She added: `I was done with the first three months by the time we started shooting. I was in the fun time where you're kind of elated and energetic and then I wrapped right before the not-so-fun time where you're sort of enormous and you can't sleep and you pee every 10 minutes.`
