Emily, 33, who is married to The Office star John Krasinski, is expecting her second child, a boy. The couple’s eldest daughter Hazel was born in 2014.
Joking with Entertainment Tonight reporter Kevin Frazier, Emily said,
“My plan is just to tell her that this is less about having a sibling and more that she's being promoted.
"She gets to have a worker now that she can boss around."
Emily and John confirmed their pregnancy in February. Since then, mum-to-be Emily has been busy on the promotional circuit as well as spending quality family time in Beverly Hills.
Emily recently also re-united with her former co-star and fellow mum Anne Hathaway for the premier of Through The Looking Glass. Anne gave birth to a son Jonathan Rosebanks Shulman on March, 24.
