Ella Purnell wears a black and white collared mini dress at the Star Trek: Prodigy screening

Ella Purnell cut a chic figure as she attended the Star Trek: Prodigy screening on Saturday in London.

The actress, 25, flashed her legs in a black collared mini dress with puffed sleeves and white ruffled detailing while wowing onlookers at the star-studded event. 

She continued her look with a pair of charcoal leather shoes while tying her sandy locks back with a coordinating headband. 

The London native, who plays Gwyn in the Nickelodeon series, painted her pout an eye-popping shade of red while accessorising with a pair of gold hoop earrings. 

Beaming for onlookers, she was soon joined by her castmates, Angus Imrie, Kevin Hageman, Dan Hageman, Kate Mulgrew, and Ben Hibon for their red carpet reunion.

She’s proved to be an inspiration to many young actors and actresses with her impressive portfolio and determined spirit.

Yet Ella recently revealed that privately she has been suffering with depression and anxiety, and has previously been struggling with self harm.

Speaking to ES Magazine, the Sweetbitter star revealed she suffered an undisclosed traumatic incident at school that became the catalyst for her mental health issues.

She admitted that she didn’t feel comfortable speaking to anyone at the time about how she was feeling, and instead turned to self harm.

The Agatha Christie star said: ‘Self-harm is not about attention — I hid [my scars] for six months, wore long T-shirts, covered them up with make-up. It’s about punishing yourself, for people who dislike themselves or suffer from insecurity or self-doubt.

‘I still have the scars and it’s something that I did that I will always regret: it hurt a lot of people around me and it’s on my body forever.’

Yet Ella is not ashamed of her past and is hoping talking about her experiences will help others struggling with mental health issues.

Ella is not slowing down with her career and will soon star in TV series Sweetbitter, based on Stephanie Danler’s novel about a New York waitress.

The role is steamier than ones she has experienced in the past, and as it involved nudity, Ella admitted she had no idea what to expect.

‘I was terrified and it was awkward as hell,’ she confessed, ‘but the most important thing for me was that it was real, that it doesn’t look like a porno, there’s no shaved things and no weird uncomfortable sexual positions, and it’s sometimes awkward and gross.’
