Warren Beatty and Annette Bening's nepo baby daughter Ella, 26, enjoys her moment in the spotlight at the premiere of her new Netflix series Monster: The Lizzie Borden Story

Warren Beatty and Annette Bening's nepo baby daughter Ella Beatty enjoyed her moment in the spotlight at the premiere of her new Netflix series in New York on Wednesday. 

The rising star, 26, looked fabulous in a figure-hugging black gown as she posed for snaps while celebrating her lead role in Monster: The Lizzie Borden Story.

Ella takes on the role of acquitted murder suspect Lizzie Borden in the hit anthology Monster series.

And the actress ensured she looked her best for her big moment, slipping into the sleek black number which featured a corset-style top and a small train.

Ella, who is the youngest child of Hollywood icons Warren and Annette, left her auburn locks to cascade over her shoulders in glamorous waves, while she kept her accessories to a minimum. 

She appeared in fantastic spirits on the night, with Ella seen giggling with her co-stars before posing with them in backstage snaps. 

Ella's debut lead role will see her portray Lizzie, who was accused of killing her parents, Andrew and Abby Borden, in a brutal hatchet attack in 1892. She was found not guilty by an all-male jury the following year. 

Ella's own parents meanwhile have one of the longest marriages in Hollywood and have credits in some of the biggest movies of the 90s to their name, including American Beauty, Dick Tracy and The American President.   

The actress was born in April 2000 in Los Angeles and is the niece of another star: her aunt Shirley MacLaine.

'I totally acknowledge that there is an inherent privilege and exposure that comes from having well-known actors as parents,' she told Vogue in 2024. 

'And I really hope that I can offer something meaningful.' 

Growing up with her famous parents meant she spent a lot of time on film sets and in dressing rooms.

So it might come as no surprise that she 'always' wanted to be an actor. 

When asked about growing up in an acting family and if they influenced her decision to become an actor she replied: 'I don't know anything else. I have no other context for the world.'

'But my parents are the most loving, supportive, incredible artists,' she said, noting they taught her to 'contextualize the world' as artists since she was 'a very little girl'. 

Growing up, she was involved in community theater and appeared in productions of the musicals Annie, The Lion King and The Little Mermaid.

Despite having family who were well connected in the industry, she didn't become a child actor.

Instead she went on to study drama at The Juilliard School in New York, where she studied under legendary instructors like Moni Yakim, before graduating in 2022.

After graduating, Ella landed her first TV role in the FX anthology series Feud: Capote v The Swans.

She starred in the period drama as Kerry O'Shea, who was the daughter of Truman Capote's lover, John O'Shea. 

She then went on to make her Broadway debut, appearing in the Branden Jacobs-Jenkins play Appropriate, replacing Elle Fanning. 

That following year, she returned to theatre to play flirtatious maid, Regina Engstrom in the production of Henrik Ibsen's Ghosts and Sexual Misconduct of the Middle Class.

She also appeared on screen in the 2025 Oscar-nominated A24 comedy-drama If I Had Legs I'd Kick You, starring Rose Byrne.

Now, Ella is returning to the screen for Netflix's Monster.

'I am so excited for viewers to experience our exploration of Lizzie Borden's story and the questions that her life animates to this day,' Ella told Netflix's Tudum in August. 

'It has been a dream come true to investigate this complicated person's psychology and to examine an American crime that feels almost mythic in proportion. ... I cannot wait to share it with the world.'

Co-creator Ian Brennan said it 'felt right' to cast Ella as Lizzie.

He said: 'She can have a real blank slate of a face.

'She exudes this sense of innocence.  There's so little photographic evidence of Lizzie, but the iconic daguerreotype of her — she's got such a strange look. 

'There's something about Ella that was able to match that inscrutability.'

Monster: The Lizzie Borden Story drops on Netflix on Thursday, September 17.
