The actress, 25, chose to go braless in a racy sheer lace top and matching flares as she took her seat on the front row.

She teamed her all-black ensemble with a pair of towering platform heels and carried a miniature silver hand bag.

Bella styled her red hair into soft Old Hollywood style curls and added a pop of colour to her look with a slick of red lipstick.

To complete her look, the star accessorised with a pair of large silver earrings and a qui0nt jacket that she teamed with a printed turtle neck top.

The daughter of Mick Jagger and Gerry Hall boosted her height with a pair of chunky velvet boots.

Bella’s outing comes after she revealed that she is not comfortable autographing all photos of herself.

The Midnight Sun actress shared a recent encounter she had with a male autograph seeker at the Sundance Film Festival where she declined signing the photos he handed her.

The star recalled the incident during which she was given racy photos of herself – some of which were taken when she was underage – and told The Hollywood Reporter she ‘didn’t like’ the situation.

‘I normally don’t tell them off but they offended me. It was this guy and he was shoving photos in front of me and I looked away for a second and looked back and there was a photo of me from my GQ magazine cover.’

‘It’s super sexy and my butt is out and I’m wearing lingerie and I’m topless,’ she explained about the photos, which were part of the 2017 GQ Mexico cover spread.

After she declined to sign the photo, the man continued to ask her to sing other content. ‘I said I wouldn’t sign that and he took it away and then put it back in front of me again. I said, “No, I’m not signing that.”‘

‘He pulled out another photo of a magazine with another sexy image. He was like, “Come on, Bella. Sign it for me.” I didn’t like it. It was inappropriate.’

The actress stated that she was uncomfortable signing the images because they were taken when she was underage.

‘There was some stuff there from a Candies campaign that I did when I was 16 and it was clear that he wanted me to sign things that were viewed as sexy and even underage and I was like, “Give me something else,”‘ she explained.
