Keira Knightley Gives Birth To First Child

Keira Knightley is officially a mom!

The "Imitation Game" actress gave birth to her first child, according to E! News and People. Knightley's reps were not immediately available for comment.

In December, Page Six broke the news that Knightley, who turned 30 last March, and husband James Righton were expecting their first child. Pregnancy rumors first began swirling in November.

While visiting "Jimmy Kimmel Live!" in February, the Oscar nominee admitted that she didn't know much about babies or motherhood. We're sure Knightley and Righton are caught up to speed by now. Congrats to the new parents!
