Keira Knightleyhit the red carpet for the premiere of her new movie,Official Secrets, in London on Thursday after quietly giving birth to her second child.

The 34-year-old actress wore a white midi-dress with embroidered flowers and puffy sleeves, accessorizing the dress with strappy gold high heels. Knightley wore her shoulder-length brunette locks in soft waves around her face for the event, where she posed for photos and took some time to sign autographs for fans.

Knightley has yet to publicly announce the birth of her second child with husbandJames Righton, and a rep for the actress did not immediately respond to PEOPLE’s request for comment.

The couple is very private when it comes to their children, but Knightley toldBalancemagazinein January that women aren’t given enough credit “for the physical and emotional marathon they go through when becoming a mother.”

“I come from a place of amazing privilege. I have an incredible support system; I’ve been unbelievably lucky in my career; I can afford good childcare, and yet I still find it really f— difficult,” thePirates of the Caribbeanstar told the outlet, adding that it “doesn’t mean I don’t love my kid.”

“It’s okay to say that,” she said. “It’s just meadmitting that the sleep deprivation, the hormonal changes, the shift in relationship with my partner, are all things that make me feel as if I’m failing on a daily basis.”

In March, Knightley toldKelly Ripaand Ryan Seacrest onLive with Kelly and Ryanthat she was dealing with a “threenager.”

“Two, we were actually fine, she was an angel,” she told the hosts, adding, “then you think, ‘Oh, I’m the best parent in the world,’ and then three happens.”

Just like Knightley’s struggle with sleep deprivation is sure to be relatable to moms everywhere, Edie’s latest obsession is also sure to have some parents rolling their eyes in mutual annoyance.

“We seem to have gotten out of that [threenager phase] and nowshe’s intoPAW Patrol,” the actress said. And while the children’s show is a great distraction for her daughter, Knightley said “it’s so annoying, the theme tune, and it’s only about 7 minutes or something so the theme tune happens a lot.”
