A complete timeline of Margot Robbie and Tom Ackerley's relationship

The romantic drama, released in 2014, starred Robbie, Michelle Williams, Kristin Scott Thomas, and Matthias Schoenaerts.

Ackerley served as the third assistant director.

Per Vogue, Robbie invited Ackerley, her childhood friend Sophia Kerr, and a few people she worked with on the set of "Suite Française" to the UK premiere of "The Wolf of Wall Street" in January 2014.

After an enjoyable night, Robbie suggested that they should all live together. So, they leased a home in London. Robbie and Ackerley began dating that year.

"We kept it a secret. Because we weren't really taking it seriously. 'Oh, whatever, we're just mates, we're just mates.' And then… everyone found out," Robbie told The Guardian in 2018.

The actor said that "shit hit the fan" when the secret came out.

"Our house turned into 'The Jerry Springer Show' for a moment there," she recalled. "But then the dust settled, and it was all good."

Robbie said that their friends were concerned that the relationship would "ruin our group."

"And then it didn't. It was fine," she said.

Robbie told Porter magazine that she's "a great advocate of doing business with your partner."

Several of Robbie's films have been produced by LuckyChap, including "I, Tonya," "Birds of Prey," and "Barbie."

When asked about the backstory of the production company's name, Robbie told The Guardian in 2018: "We were just drunk. We were here when we came up with it. And nobody can remember why. I think we were talking about Charlie Chaplin…"

Ackerley's Instagram account featured photos of the couple and he gave Robbie a shout-out after she landed a Critics Choice Award for best actress in an action movie for her role as Harley Quinn in "Suicide Squad."

They also attended New York Rangers games at Madison Square Garden in November 2014 and February 2015.

Robbie is actually a big fan of ice hockey and was briefly part of a league when she moved from Australia to New York.

Robbie called the British producer "the best-looking guy in London" and explained how their dynamic turned romantic.

"I was the ultimate single gal," Robbie told Vogue. "The idea of relationships made me want to vomit. And then this crept up on me."

"We were friends for so long," she continued. "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."

Rumors had swirled regarding the couple's relationship status — particularly when Robbie was seen arriving at the Gold Coast Airport while wearing a T-shirt that read, "Say 'I Do' Down Under."

The "Birds of Prey" star reacted to the speculation by posting a caption-less photo on Instagram that spoke for itself (Robbie's Instagram account has since been deleted).

The photo showed Robbie and Ackerley dressed in white attire and kissing, but the focus of the image was the pear-shaped engagement ring and thin gold wedding band on display on the fourth finger of her left hand.

The wedding reportedly took place at Coorabell, Byron Bay, Australia. Robbie later revealed to MTV News that she walked down the aisle to music from the 1993 film "True Romance."

Ackerley produced "I, Tonya," which starred Robbie as controversial figure skater Tonya Harding.

Robbie spoke about their decision to work instead of going on vacation during a 2017 interview with Extra.

"We did this film instead of our honeymoon," she said. "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."

After filming "I, Tonya," Robbie and Ackerley went to Tahiti for their honeymoon — where they ran into Ellen DeGeneres, her wife Portia de Rossi, and Barack Obama.

Robbie recalled their embarrassing encounter on the private island during an appearance on "The Ellen DeGeneres Show" in January 2018.

The two couples and the former president of the US ended up together at a gym on the island, and the experience was particularly embarrassing for Ackerley because he chose to wear extremely short, baggy shorts with nothing underneath.

"The whole thing was so absurd," Robbie said, explaining that Ackerley spent the entire stretching class trying not to reveal himself to the other famous people in the small gym.

"My husband and I were roommates before we were even dating, so I'm kind of living with my roommate and it's awesome," she told the publication at the premiere of the film "Goodbye Christopher Robin" in NYC.

Robbie added that the pair "feel very grown up now" with their new living arrangement.

"Great way to bring in 2018!" Ackerley captioned a selfie of the pair on the slopes in their snow gear.

"I, Tonya" was nominated for three awards: best actress in a leading role (Robbie), best actress in a supporting role (Allison Janney), and best achievement in film editing.

Ackerley, who produced the movie, shared his enthusiasm for the Oscars by posting a photo of himself and Robbie with several crew members.

At the show, Janney won the award she was nominated for.

Robbie and Ackerley walked the red carpet of the Academy Awards together, in addition to attending the Vanity Fair Oscars after-party.

They rescued the mixed pitbull from Wags and Walks Rescue, a non-profit.

Belle joined the couple's other dog, Boo Radley, who is named after the character from Harper Lee's "To Kill a Mockingbird."

"I always thought, 'Urrgghhhh, being married sounds really boring.' I thought I might bite the bullet in my late 30s and see how it goes," Robbie told Porter magazine.

Of course, her outlook changed once she met and wed Ackerley.

"Being married is actually the most fun ever, life got way more fun somehow," Robbie said. "I have a responsibility being someone's wife, I want to be better."

The actor also said that they have a three-week rule whenever they're apart from each other. It involves talking on the phone every day and flying to a country in-between their locations so they can spend time together.

Robbie also said that she wasn't looking to expand their family by having children yet, since two dogs are enough of a responsibility.

"If I'm looking into my future 30 years from now, I want to see a big Christmas dinner with tons of kids there," she said. "But definitely not at the moment. That's 100% certain."

Robbie described her husband as a "very loud and friendly person."

She also reiterated that she enjoys working with him professionally.

"We can talk about work all the time," she said. "And then work feels like fun. And fun stuff can involve work."

"We just get along," Robbie added. "I think it's crazy that not all couples get along."

That year, Robbie was nominated for best performance by an actress in a supporting role in a motion picture for her work as Kayla Pospisil in "Bombshell."

"My husband is in the 'Harry Potter' movies," Robbie said during an appearance on "The Graham Norton Show."

"He was an extra when he was a little kid — he was one of the Slytherin extras when Draco pushes some kids out of the way to see Buckbeak in the third book," she explained. "He pushes my husband out of the way."

"I was like, 'Had you told me sooner we would've been married very quickly,'" Robbie joked.

Greta Gerwig's "Barbie," which hit theaters on July 21, stars Robbie as Stereotypical Barbie. After a series of weird experiences in the perfect, pink-laden Barbieland, Robbie's character travels to the real world.

Ackerley has a producer credit on the film and accompanied Robbie to a press junket and photo call for "Barbie," which took place at the Four Seasons Hotel Los Angeles at Beverly Hills on June 25.

He also showed up to a celebration party at the Museum of Contemporary Art in Sydney, Australia on June 30; the world premiere of "Barbie" in LA on July 9; and the European premiere at Cineworld Leicester Square on July 12.
