Margot Robbie is pregnant, expecting her first child with husband Tom Ackerley

Margot Robbie has starred in major movies like Barbie, The Wolf of Wall Street, and Suicide Squad, and now she's embarking on what might be her biggest project yet: motherhood.

The 34-year-old actress and producer was spotted with a baby bump in Italy over the weekend, and multiple sources have confirmed to PEOPLE that Robbie is pregnant, expecting her first child with husband Tom Ackerley.

Representatives for Robbie didn't immediately respond to Entertainment Weekly's request for comment.

Robbie and Ackerley, who's also 34, met on the set of the romantic drama Suite Française in 2013; he was an assistant director on the film and she was part of the cast, alongside Michelle Williams and Kristin Scott Thomas. The couple wed three years later.

Ackerley and Robbie went on to co-found the production company LuckyChap Entertainment, which has been behind the scenes of hit movies including Promising Young Woman, Saltburn, and, yep, Barbie.

Though they tend to keep their relationship private, Ackerly recently spoke to the Sunday Times about Robbie. For the couple, he said, keeping business and their personal relationship apart is "seamless," which is fortunate because they spend "24 hours a day" together.

"We don't have a toggle on, toggle off," he added. "It's all become one thing."

As far as children, Robbie told the Daily Telegraph in her native Australia back in 2016 that she was looking forward to having a big family.

"I grew up in a family of four [kids], so that sounds like a good number," she said. "We'll see what happens; no time soon. I know that once I have kids, they'll be my priority, so I want to do the family thing later."
