According to the People Magazine, the Oscar nominee, 32, made her first public appearance after giving birth at a cast dinner for her new film 'Mudbound' at the Toronto International Film Festival on Monday.
While appearing at a press conference for her new movie Mudbound, Mulligan was asked about being a mother of two.
She said, "It's good, thank you."
The 'Pride & Prejudice' actress and the 'Mumford & Sons' lead singer tied the knot in Somerset, England, in April 2012.
They were childhood pen pals before their friendship turned romantic in 2011.
This is the second child for Mulligan and Mumford. The couple also has a young daughter named Evelyn Grace Mumford, who was born in 2015.
