Paris Hilton and Nicole Richie are ready to rule reality TV together once again.

The Hilton heiress, 43, and the fashion designer, 42, famously starred on The Simple Life from 2003 until 2007, where they traded in Hollywood glitz for small-town America, and are now working together on a new show as per TMZ.

The premise of the series has not yet been revealed, though production sources shared that it’s not going to be an exact copy of their former show, nor will it have the same name.

Paris and Nicole have already sold their pitch to a streamer, after reportedly talking about the project for months and trying to figure out ideas on how they could work together again.

The show is still in early development, and nothing has been shot as of yet.

The pitch reportedly incited an ‘all-out bidding war’, with James Corden’s production company, Fulwell 73, eventually buying the rights to shoot it.

Paris — who featured on a heartbreaking new Sia song called Fame Won’t Love You last month — and Nicole seemed to be hinting at something on Wednesday as they both shared a nostalgic throwback collage of snaps showing them together.

They both captioned the post, ‘From Day 1: Sill and Bill,’ referring to their nicknames for each other.

Paris and Nicole became household names over 20 years ago in the early 2000s after starring on The Simple Life for a total of 5 seasons. The series aired between FOX and E!.

The show’s premise revolved around taking the two rich socialites out of their comfort zones and putting them in everyday working-class situations, creating culture clash comedy.

The socialites were seen taking on laborious jobs like cleaning, doing farm work, and food service.

The show remains a beloved reality TV series among fans, and produced Paris’ iconic line ‘That’s hot!’

Another famous moment took place at supermarket Walmart, where Paris questioned, ‘What is Walmart? Do they sell wall stuff?’

The show celebrated its 20th anniversary last year.

For the occasion Hilton posted a number of throwback photos of herself and Richie on Instagram.

‘Happy 20th anniversary to [the] show that started it all, The Simple Life! Filming this series with @NicoleRichie was one of the most special, hilarious, and iconic times in my life. I’m so lucky to have these amazing memories!’ she wrote in the caption.

Richie also marked the occasion, sharing a reel of some of her and Hilton’s Simple Life highlights.

’20 years ago, not only did we become television stars… we became songwriters,’ she humorously wrote in the caption. ‘Happy Anniversary Sill @parishilton.’

Last month Nicole admitted that her teenage children refuse to watch reruns and clips of The Simple Life, as it makes a comeback on TikTok.

The actress told Variety that her son Sparrow, 14, and daughter Harlow, 16, are not fans of her earlier TV work as it interferes with how they see her as a parent.

‘The Simple Life is apparently having a big moment on TikTok, so they do tell me that they watch clips on TikTok,’ the actress said of her kids.

‘Their friends watch it. I get a lot of eye rolls in my house all the time. It’s right on brand with how they see me, in general.’

She added that although she has spent her life in the entertainment industry, she is unsure if it is a path her own two kids will pursue.

During the Simple Life Paris and Nicole were both single gals in their twenties.

Now, they are both married with children.

Nicole shares her two kids with rocker husband Joel Madden, 45, the lead vocalist of Good Charlotte.

Meanwhile Paris shares son, Phoenix, one, and daughter, London, born in November 2023, with entrepreneur husband Carter Reum, 43. The pair tied the knot in 2021.
