Jessica Simpson opens up about working with Kim Kardashian in 'All's Fair'

Jessica Simpson revealed she had a 'blast' filming her cameo in "All's Fair."

In a recent with Entertainment Tonight, Jessica opened up about working with Kim Kardashian in Ryan Murphy's new legal drama.

Sharing insights into her guest appearance on the series, the 44-year-old singer revealed that her character took hours of preparation to bring to life.

“I had a blast,” she remarked. “I did eight hours of prosthetics, so it was very intense. but props to the prosthetics team. I love you guys so much. They said I had the most patience of anyone they've ever worked with, so, I mean, that's a good compliment. I really embody someone that I am not, so I was definitely acting.”

Talking about sharing the screen with the reality TV star, Jessica noted, "Kim, I mean, we just live down the street from each other. Our kids are best friends, so to be on set, it just felt kind of natural. It was fun to work together — we've never worked together.”

“She did all the lawyer talk, I did all the whining,” she said jokingly.

Other notable cast members starred in the series Naomi Watts, Glenn Close, Teyana Taylor, Sarah Paulson, and Niecy Nash-Betts.
