Demi could be seen with various different pieces of ink across her back including one rather large central piece.
They continued down to her behind as her metallic coloured thong covered the ʙoттoм of the inking.
Her figure looked sensational as the tiny ʙικιɴι protected her modesty as she soaked up the sun.
Completing her futuristic ʙικιɴι look, she added a unique pair of sunglᴀsses that appeared to replicate a pair of goggles as well as a metal chin piece.
The reality TV star captioned the pics: “3023.”
One fan clearly understood Demi’s fashion mission as they commented underneath the post: “Back to the future.”
Keen to compliment the star, another adoring fan added: “Unreal.”
Another penned: “So H๏τ love it!”
As a fourth shared: “This is sickkkk.”
It comes as the first-look trailer for Demi and her family’s new reality show, House of Sims, circulated online.
The reality TV show follows the family as they move to LA in order to kickstart their US careers.
ᴀᴅuʟт subscription site OnlyFans has backed the project and will be bringing the show to life via their TV app platform, OFTV.
Demi will appear on the show alongside 40 year old sister Chloe and Frankie, 27.
The Sun previously revealed the family landed half a million to film House Of Sims and they’ve already been signed for a second series.
An insider told The Sun: “OnlyFans TV bosses hugely believe in Chloe and her sisters Frankie, Demi, and their brother Charlie.
“They’ve got loads of cash to splash on talent, and understood the family are bringing their own fanbase along with them from years of being on Towie.
“It was a no brainer to lock them down for more seasons.”
The show source revealed that the family are “loving” their new life across the pond, despite a “huge adjustment”.
