Emily Mortimer: New Daughter May Is "Very Advanced"

Actress Emily Mortimer was on the red carpet for the New York premiere of her new film Shutter Island, though the mom-of-two admits it was hard to leave her new daughter May behind.

“The new baby is so sweet,” the British-born actress told OK!. “It’s heartbreaking leaving her [for the] evening. I feel like it’s going to be such a long night, but I can’t wait to see the movie.”

The proud mama - who recently confessed to dining on raw chicken during her last pregnancy - was happy to boast about the family's newest addition: “She’s smiling. She’s very advanced. She’s only a month old, but she’s very advanced.”

Emily also revealed that her 6-year-old son Sam is adjusting well to his new role as a big brother - for the most part.

“He’s being very, very sweet to her," she says. “He’s very into the baby. He’s not so much into me being into the baby. I have to pretend not to like the baby very much or my son will [get upset].”
