Carey Mulligan has given birth

Carey Mulligan has given birth to a "happy and healthy" baby.

The 30-year-old actress - whose pregnancy was revealed in April - and husband Marcus Mumford welcomed their first child into the world recently and the British star made her first public appearance since giving birth at the BFI London Film Festival earlier today (06.10.15).

A source told E! News: "Carey have given birth to a healthy and happy baby. She is just enjoying this time with her family and close friends."

The fiercely-private actress wore mixed prints as she posed to promote her new film 'Suffragette' with co-star Meryl Streep, director Sarah Gavron, screenwriter Abi Morgan and producers Alison Owen and Faye Ward.

Though she didn't comment on changes in her personal life, Carey spoke of how she feels her new film - about the women's suffrage movement of the late 19th and early 20th century - feels relevant to modern society.

She said during the press conference: "What I love about this film is it didn't feel like a documentary about a time; it felt like a film about today.

"It is a film to mark the achievements of what these women did and what they gave us but also to highlight where we are in the world. We still live in a society that is sexist and that goes throughout history."
