Motherhood is fantastic for Margot Robbie.

More than nine months after giving birth to a baby boy with husband Tom Ackerley, the Barbie star is relishing her new life as a parent. So much so, she's having a hard time putting her joy into words.

"It's funny, you try to explain to someone who has kids, you don’t need to because they get it," Margot told Entertainment Tonight in a video published Aug. 20. "And if they don’t, it’s probably just really boring to hear."

She added of being a mom, "It's the best."

While Margot hasn't shared much about her son, including his name, she's taken the title of being her little one's mother to heart. In fact, the 35-year-old—who married Tom in 2016—was spotted wearing a gold chain necklace reading "mama" during some downtime in her native Australia earlier this year.

Margot's pregnancy with her first child came following the booming box office success of 2023's Barbie. Now returning to the big screen alongside Colin Farrell in A Big Bold Beautiful Journey, she recently quipped, “That’s the longest break I’ve ever had between jobs."

"I thought it would be more scary to be walking onto the Big Bold set on day one, but it wasn't,” she told Vanity Fair in a June interview. “Everything about this film was immediately comfortable."

She continued of the project's romance story, "If audiences feel even a tiny slice of how magical it felt making this movie, then they’ll have the most incredible experience in the theater. Making this movie was truly one of the most magical experiences of my life."

As for her costar? Colin's parenthood journey has been nothing short of a wonder as well.

“It’s meant everything to me," The Penguin actor—who is dad to sons James, 21, and Henry, 15—told Entertainment Tonight during their joint interview. "They are the most important facet of my life and have been since they came into being."

He added of his kids, "They’ve taught me so much. Whoever I am today, it’s in great part to do with their involvement."
