The Australian actress reportedly went into labour two weeks ago and has now had her first child, People reported. The exact time of birth has not been disclosed.
The new parents, both 34, are set to spend time with their son, whose name has not yet been revealed. Robbie is next lined up to star in Emerald Fennell’s upcoming adaptation of Wuthering Heights.
In recent years, Robbie has increasingly turned to producing, most recently acting in and producing Barbie.
She and Ackerley married in 2016 and currently live in Venice Beach, California.
It was revealed in July that the Oscar-nominated actress was pregnant after she was photographed carefully boarding a boat during a holiday in Lake Como with her husband.
Robbie and Ackerley met in 2013 while filming Suite Française, a World War II romantic drama in Belgium, where he was an assistant director and she starred as Celine.
Known for keeping their personal lives private, the couple did not announce their engagement and were married in a secret ceremony in Byron Bay, Australia.
They were both last seen in public in September when they attended the premiere for the Aubrey Plaza-led comedy My Old Ass. Both Robbie and Ackerley were among the producers for the film.
Ackerley recently offered a rare comment about their relationship, having been asked how the star couple balance their work and home lives.
He told the Sunday Times in June: “[We spend] 24 hours a day [together]. It’s seamless. We don’t have a toggle on, toggle off. It’s all become one thing.”
Previously, Robbie revealed that her relationship with “the best-looking guy in London” was unexpected.
She told Vogue in 2016: “I was the ultimate single gal. The idea of relationships made me want to vomit. And then this crept up on me. We were friends for so long. I was always in love with him.
“But I thought, ‘Oh, he would never love me back. Don’t make it weird, Margot. Don’t be stupid and tell him that you like him.’
“And then it happened, and I was like, ‘Of course we’re together. This makes so much sense, the way nothing has ever made sense before.’”
A year after meeting, they co-founded the production company LuckyChap Entertainment, which has produced major films including Barbie, I, Tonya, and Birds of Prey.
