Margot Robbie says the idea of a relationship made her want to "vomit" before she met Tom Ackerley.

She said: "I was the ultimate single gal. The idea of relationships made me want to vomit. 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.'"

And it's not only a personal relationship the couple have, they are also business partners and run their own production company called LuckyChap alongside Tom's friend Josey McNamara and Sophia Kerr, a close pal of Margot.

The 25-year-old actress added of their venture: "We chose the most challenging indie film imaginable - it’s not commercially viable from a financier’s point of view. It’s shaving years off my life. "It’s really hard work, but so rewarding and much more empowering than just acting. I was starting to feel like a little pawn getting moved around the board: Go here! Do that! Be her!"

Meanwhile, Tina Fey - who stars alongside Margot in 'Whiskey Tango Foxtrot' - praised the actress for getting on the "front foot" in her career by setting up her own company.

Of Margot, Tina told Vogue magazine: "This is a very smart thing for her to do because otherwise, as a piece of casting, she’s always going to have someone saying, ‘You look amazing - but we’d love for you to weigh less.’ Already at 25 she’s like, 'You know what? I’m going to opt out of that f***ery and be on my front foot with my career."
