BREAKING: Congrats are in order for Keira Knightley this evening!

It feels like no time at all since actress Keira Knightley revealed she was expecting, but she has already welcomed her new arrival to the world.

The Imitation Game star has given birth to her first child with husband James Righton, it's being reported this evening. 

No name or sex has been revealed as yet, but E! News have confirmed the news is indeed true.

The couple have been married since May 2013, and although Keira never officially confirmed she was expecting, it was abundantly clear when she stepped out on the Golden Globes red carpet back in January.

Although her white Victorian-style Chanel creation at the Globes (above) received some criticism for being too "frumpy," Keira knocked it out of the park at the Screen Actors Guild Awards two weeks later in an incredible deep purple number by Erdem.

The floor-length dress featured mesh inserts and a bandeau style back.

Speaking on Jimmy Kimmel Live shortly after the awards, the actress joked that she was "in denial" about her pregnancy, responding to the host's questions about her baby preparation by saying, "They're quite small though right? Do they need a room of their own?"

We hope she has sorted out a room by now…

Keira was spotted out and about in London with James last month looking almost ready to pop, rocking summer maternity style in a flowing red skirt and cropped black jumper.

We can't wait to see the first pictures of the little one!
