British actress Emily who is married to actor John Krasinski turned out with the cast of her new film at the premiere for The Huntsman: Winter's War in Los Angeles on Monday (11Apr16). When asked if her daughter was looking forward to having a sibling she revealed Hazel wasn't fully on board with the plan.

"She's a bit dismissive of the idea at the moment," Emily told Entertainment Tonight. "She's quite liking being top dog."

While she admits her daughter "has no choice" but to accept it, the actress revealed she has an innovative way to help Hazel come to terms with her new normal.

"My plan is just to tell her that this is less about having a sibling and more that she's being promoted," Emily joked. "She gets to have a worker now that she can boss around."

The British actress plays Freya, a royal sorceress with freezing powers in the new movie loosely based on the Snow White fairytale. Freya is the sister of the evil Queen Ravenna - played by Charlize Theron - who becomes a feared icy enchantress at the start of the new movie after a tragic event awakens her magical powers.

In the film the Devil Wears Prada star wears some ornate and intricate handmade costumes, which were almost more difficult to carry around than her growing baby bump.

"With the bump you sort of adjust slowly as you get heavier, but with the dress its just like someone kind of drops a bear over your back to carry," Emily explained.

"There was like a huge leather cloak I wore that was made out of braided leather. You know it's heavy when you see four men wrestling it onto the set."

The Huntsman: Winter’s War is out now in the UK and hits theatres in the US on 22 April.
