Keira Knightley has reportedly given birth to her first child.

The British actress and husband James Righton, 31, recently welcomed their baby into the world in London, according to E! News, but no further details have been confirmed yet.

The 30-year-old star, who got married to the Klaxons rocker in France in May 2013, previously admitted she was feeling relaxed about becoming a mother despite struggling to come up with a ''whole birthing plan.''

The 'Pirates of Caribbean' beauty said: ''There isn't an option to sort of keep it in, is there? So, I'm assuming my plan is to get it out. But apparently there's more to the plan than that. I don't know what that is. Still, my plan is to get it out. It will come out.''

The Oscar-nominee also joked James was enjoying ''drinking for two'' while she was pregnant.

Speaking about how she's using her pregnancy as an excuse to make him attend awards season parties with her, she said: ''I'm [telling him], 'You have to come with me, support me!

''There's a lot of free champagne [at events], so he thinks because I'm not drinking, he has two. I'm eating for two and he's drinking for two.''

Keira's 'The Imitation Game' director Morten Tyldum recently predicted she would be a ''wonderful mom.''

He added: ''She's a wonderful person! She's so sincere, so loving and her husband is great and they're such a great couple.''
