Margot Robbie's husband shares rare insight into their marriage

Tom Ackerley has opened up about his notoriously private marriage to Margot Robbie, revealing the one thing the pair clash over at home and how they separate business and pleasure.

Of course, we know Robbie as a Hollywood actor, perhaps most recognised for her roles in Barbie and The Wolf of Wall Street.

Ackerley - full name Thomas Francis Michael Ackerley - also works in film as a producer, actor, and former assistant director.

Ackerley is also a co-founder with Robbie of the production company LuckyChap Entertainment - used for films such as I, Tonya, Barbie and Saltburn.

The couple met in 2013 on the set of Suite Française, began dating the year after and then tied the knot in 2016.

During an interview with The Times, the couple spoke about what their relationship is like and how they somehow manage to spend '24 hours a day' together.

When asked about how they separate business and pleasure, Ackerley said: "It’s seamless. We don’t have a toggle on, toggle off. It’s all become one thing."

Apparently there's no arguments either, with Ackerley saying he 'feels like an honorary Aussie, Margot feels like an honorary Brit', though he does 'wish there was more of a sporting rivalry' between the couple's country of origin.

The only disagreement the couple seem to have is over chocolate biscuits, and I think we can all relate to that.

Robbie has also opened up about her marriage in the past, telling Porter: "I’m a great advocate of doing business with your partner.

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

Discussing further in a 2016 interview with Vogue, the Barbie actor spoke about how the pair developed a close friendship after meeting on a film set before becoming romantically involved.

She said: "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 film-loving couple will celebrate their eighth wedding anniversary in December this year.
