“I have a bit of a lava lamp fetish. They are kind of hideous, but there is something so therapeutic about them.”

I think working in the industry, I’d be pretty nervous to have a celebrity crush.

I did get a letter which was pretty alarming once. Well, it was sent to the Fifty Shades production office. And it was pretty … I’d say interesting. I don’t really want to go into that. But otherwise the response has been good, thankfully.

I did dancing and singing when I was little, and then when I was 12 years old my friends were taking speech and drama at school. They were private lessons, and I started doing that. Over the years everyone else dropped out and I just kept going. I loved it.

In Australia, everyone gets a nickname and people started calling me “Izzy” and I hated it so I just adopted Bella.

I was always into performing and dancing as a kid and acting was a safe place to have all my feelings, which is good as a child.

I’m just a psycho myself. I loved playing Leila [from Fifty Shades Darker], taking on [a character] who’s completely unhinged. I saw her as a girl who’s grief-stricken and she just doesn’t have the tools to cope. Grief and heartbreak, it makes you do some pretty crazy things.

I think there is something about L.A., fortunately: once you get one role people think, ‘Oh well, someone employed her, so maybe we can.’ I mean, that’s my idea of it, anyway. ‘She can put one foot in front of the other and say a line.’

I collect skulls; I think that a beautiful skull is a really good gift for a guy.

I think working in the industry, I’d be pretty nervous to have a celebrity crush. I’d be pretty nervous if my boyfriend did as well because inevitably you’d end up working with them and then it would feel very suspicious.

All my stuff is men’s fashion. It’s always oversized shirts, boyfriend blazers and trousers.

I don’t really cook meat. I eat a bit of seafood but I’m not really into meat and the idea of cooking it is pretty intense.

I first got into acting when I was about 12. I started doing speech and drama lessons. All my friends were doing it at the time and my dad encouraged it. He encouraged any extracurricular activity.

I was a huge nerd in high school. Sure, I socialized – but I was definitely a nerd.

[Fifty Shades Darker director] James Foley directed Fear. And that’s what I love about this film, because it has a real sexy thriller element about it.

Acting is different all the time. When you’re on set, different films, or just even in between, it’s never the same. I think that’s one of the things I love about it.

I kind of liked all the creeping stuff [in Fifty Shades Darker], like when they’re sleeping and there’s me just standing behind the bed. It was great.

I was always doing beauty blogs about nails, and it would be on Fridays called Fridays Fingertip Fetish.

It became so popular that a nail polish company approached me, and Fingertip Fetish was born.

I have an odd fetish with nails.
