Hollywood actress Keira Knightley has become a first-time mother after reportedly giving birth.

According to E! News, The Imitation Game star has welcomed her new addition with husband James Righton.

Although no further details have been made available, Knightley previously told Ellen DeGeneres that she was looking forward to being able to have an alcoholic drink.

"When can I drink? Please?" she joked to the talk-show host during an appearance earlier this year. "I just want a margarita! What other moms can relate to that?!"

She also admitted that she didn't have a birthing plan and was focusing on just getting it out.

"There isn't an option to sort of keep it in, is there?" she quipped. "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."

Knightley, who married Klaxons singer Righton in a small ceremony in Provence, France in spring 2013, confirmed her pregnancy after weeks of speculation in December 2014.

The 30-year-old star had previously opened up about her preferred parenting style in an interview with Vogue saying: "I don't want to deny my femininity. Would I want to be a stay-at-home mother? No. On the other hand, you should be allowed to do that, as should men, without being sneered at."
