Billie Lourd and Ella Beatty, who co-star in the fourth season of Ryan Murphy’s Netflix anthology series Monster: The Lizzie Borden Story, have spoken about the unique bond they share, largely shaped by their famous families. The show, which premiered on Netflix on September 17, portrays Lourd and Beatty as the fictional sisters Emma and Lizzie Borden, dramatizing the real-life 1892 murders of Andrew and Abby Borden in Fall River, Massachusetts. The series is part of Murphy’s ongoing Monster franchise, which explores true crime stories with a dramatic twist. Lourd, 34, is the daughter of the late Star Wars actress Carrie Fisher and Hollywood talent agent Bryan Lourd. Beatty, 26, is the youngest daughter of Oscar-winning actor Warren Beatty and five-time Oscar nominee Annette Bening. In an interview with The Times of London, Lourd shared that she and Beatty often joke about their family ties, recalling that her mother, Carrie Fisher, had her first film role with Warren Beatty in the 1975 movie Shampoo. The connection between their families adds a layer of personal history to their professional collaboration. Lourd also reflected on her relationship with her late mother and grandmother Debbie Reynolds, who passed away just a day after Carrie Fisher in 2016. She described how she observed their extravagant and sometimes chaotic lives, learning from their experiences and helping her mother during difficult times. Lourd has previously worked with Ryan Murphy on projects like Scream Queens and the American Horror Story franchise, making this collaboration with Monster a continuation of her long-standing partnership with the showrunner. Beatty, who made her first leading television role in Monster, has been open about the advantages and challenges of her background. In a 2024 interview with Vogue, she acknowledged the privilege and exposure that come with having well-known parents but expressed a desire to offer something meaningful through her work. Before Monster, she graduated from Juilliard in 2022 and made her professional debut in Murphy’s Feud: Capote vs. The Swans in 2024. She also appeared on Broadway in Appropriate and in the upcoming 2025 film If I Had Legs I’d Kick You.
