Emily Blunt left baby behind for whirlwind premiere trip

British actress Emily Blunt had to leave her newborn baby daughter with husband John Krasinski on Wednesday (28May14) so she could embark on an ambitious trip to launch her new film in three countries in one day.

The actress, who became a first time mother in February (14), has teamed up with her Edge of Tomorrow co-star Tom Cruise on a seemingly impossible mission to attend premieres of the film in London, Paris in France and New York within 24 hours.

Blunt and Cruise launched the stunt by hosting an early morning red carpet session in London on Wednesday, and she told reporters she had to leave her little girl Hazel at home during the premiere marathon.

Speaking to TV show Lorraine, Blunt says, "She's gorgeous of course, I'm obsessed with her... She's with Daddy right now though, I don't think she would have done very well with the 24-hour whirlwind!"

Blunt also explains months of sleepless nights since Hazel's birth have prepared her for the tiring 24-hour jaunt, adding, "That's why I'm actually going to be in better shape than anyone else on this 24-hour whirlwind because I'm used to no sleep. Tom will look terrible by New York!"

The stars wrapped up the London premiere before heading to Paris for the second screening of the day. The mammoth promotional trek will end with a showing of the sci-fi movie in New York City on Wednesday night.
