This Barbie is going to be a great mom.

At least that’s what writer-director Megan Park thinks about Margot Robbie after working with the Barbie star on the new movie My Old Ass.

“They’re going to be the best parents ever,” Megan exclusively told E! News correspondent Will Marfuggi about Margot and husband Tom Ackerley at the Los Angeles premiere of the film on Sept. 5. “They’re amazing.”

And Megan—who is also in the process of working with Margot and Tom on other projects—doesn’t think the couple only have the makings of great parents, but also impressive filmmakers. In fact, she called them “super involved” as producers on the set of My Old Ass, which hits select theaters Sept. 13 and opens nationwide Sept. 27.

“They’ve just been the most incredible producers through this whole process,” she continued. “They give their directors and their writers so much creative freedom and space to do their thing, but they’re also super hands-on when you need them to be.”

Megan also admitted that the producing pair—who attended the My Old Ass premiere alongside their LuckyChap Entertainment producing partner Josey McNamara—were fun to hang out with while filming the comedy in Ontario, Canada.

“They were up there with us filming the movie,” she explained. “We were all riding boats together, having a blast.”

As for actress Maisy Stella—who stars alongside Aubrey Plaza in the coming-of-age movie—she also regards Margot very highly.

“She’s like quite literally such a gem and was so good to everyone,” Maisy told E! News in an interview airing Sept. 10 at 11 p.m. “She’s so thoughtful and so kind and so good at what she does. She’s an actual genius.”

Maisy also found Margot to be down to Earth when visiting set.

“She had come to set and she literally looked like a camp counselor,” Maisy said about the I, Tonya actress. “She had two braids in and was in jeans and a T-shirt and I was like, ‘Wow that’s the most beautiful woman who’s ever lived and she’s just like hanging.’”

News broke back in July that Margot—who married Tom in 2016—is pregnant with her first child after she put her baby bump on display while vacationing in Lake Como, Italy with her husband. Since then, the pair have made a few public appearances, including attending Wimbledon in style in July, with her showcasing her baby bump in a white Alaïa midi dress. The couple was also seen vacationing in Italy in August, when Margot sported a white button down that draped open to reveal her baby bump.

Tune in for more from the My Old Ass premiere on E! News Sept. 10, and read on to see Margot and Tom’s love story and path to parenthood.

After meeting on the set of Suite Française, Margot Robbie and Tom Ackerley co-founded a production company called LuckyChap Entertainment alongside friends Josey McNamara and Sophia Kerr.

The business partners lived together in a three-bedroom house in London's Clapham neighborhood which they shared between seven people. 

While living under the same roof, the actress and third assistant director went from friends to something more.

“We kept it a secret because we weren't really taking it seriously,” she told Elle in a 2018 interview. “’Oh, whatever, we're just mates, we're just mates.’ And then… everyone found out.”

The couple confirmed their romance during a PDA-outing to a New York Rangers game in February 2015.

Robbie revealed that she was always in love with Ackerley and initially thought her feelings toward who she describes as “the best-looking guy in London” were one-sided.

“I was the ultimate single gal. The idea of relationships made me want to vomit," she told Vogue.  "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.'” 

The longtime couple tied the knot during a private ceremony in Australia’s Byron Bay.

Robbie raised eyebrows while wearing a shirt that read “Say I Do Down Under,” before officially confirming the nuptials by flashing her sparkling ring finger post-wedding.

The pair, who co-produced the Oscar winning film I, Tonya, revealed that they delayed their honeymoon to shoot the movie.

“We did this film instead of our honeymoon,” Robbie told Extra. “There were times we were sitting in a car parked in Atlanta freezing cold being like, 'We should be on a beach right now. We should be on a honeymoon. What are we doing?!' Following our dream.”

Ackerley joined Robbie, who wore a stunning outfit inspired by the 1961 “Solo in the Spotlight” edition of Barbie, at the world premiere of Barbie and stayed by her side throughout the press tour. 

The duo enjoyed a vacation for the first time since the Barbie press tour sharing a passionate kiss in the Grecian waters. 

While the couple prefers to keep their romance out of the spotlight, Robbie praised her “normie” husband at the 2024 Critic’s Choice Awards.

"I am so lucky," Robbie told E! News' Chief Correspondent Keltie Knight on the red carpet. "He likes being behind the camera. He's not fazed by any of this stuff."

Ackerley attended the Academy Awards for the first time as a nominee, experiencing it with Robbie - who has been nominated for three Oscars - by his side.

"It's amazing," he told A Frame. "It's obviously incredibly overwhelming at times, but it's such a celebration of cinema. And being at the center of it, it's a dream come true, truthfully."

Barbie received eight nominations in total, including Best Picture.
