This comes after Kardashian is set to star as a character based on the celebrity lawyer who represented her amid her divorce from Kanye West in a new drama.
The 43-year-old reality star has been showing off her acting chops in American Horror Story, portraying PR Siobhan Walsh, alongside Emma Roberts, Matt Czuchry and Cara Delevingne.
It was also recently reported that Kim’s comedy film The 5th Wheel, which she is to star in and produce, has been sold to Netflix.
She’s also voiced the poodle Delores in a pair of Paw Patrol films.
And now, Deadline reports that Hulu – the streaming platform that airs her family’s show ‘The Kardashians’ – has a new legal drama based on celebrity divorce lawyer Laura Wasser on the way with Kim, who has personal experience to draw from after training to become a lawyer, in the lead role.

As well as Kim, Wasser has represented Ryan Reynolds, Angelina Jolie, Britney Spears, and Kevin Costner.
The script comes from Brothers and Sisters creator and playwright Jon Robin Baitz and is executive produced by Ryan Murphy.
Kim and momager Kris Jenner, 68, are also executive producers.
The production is seeking an ‘A-list actor to play’ Kim’s ‘onscreen love interest’ and her law partners.
Filming is scheduled to begin towards the end of 2024, with a 2025 premiere date being eyed.
Kim landing more roles comes after Kris raised concerns about her daughter having too much on her plate in the latest season of ‘The Kardashians’.

The businesswoman completely forgot a whole part of her day where she met fans and told them all about her brand SKIMS’ secret plans because she was suffering from the signs of burnout.
On a recent episode of The Kardashians, she had rehearsals for her role in American Horror Story, a Time magazine cover shoot, a Met Gala dress fitting, a SKIMS business meeting, a fashion gala, an appearance on the ‘Today’ show, and watched her brother-in-law Travis Barker’s Blink-182 show.
However, there is one part of her day she completely forgot, greeting fans at the Tiffany’s store and sharing where she was on social media.
She said whilst showing the footage: ‘I had no idea that I stopped at the Tiffany’s store and was posting all about it.
‘Did I really go? It felt like a dream. This whole morning has been a complete, foggy dream.’
Momager Kris, 68, was concerned about her daughter burning out and quizzed her over her schedule.
Kim admitted doing ‘American Horror Story’ ‘put me over the edge’.
