The mother-daughter team, who were hunkered down in a tropical island retreat with their nearest and dearest for Kim’s 40th, posed on the beach in all their finery.
The group of less than 30 people jetted out on October 20, returning five days later.
Kim rocked a figure-hugging orange printed number, while momager Kris embraced a flowing white summer dress.
“Now that I have your attention…” Kim wrote, “this a reminder to VOTE. 6 days.”
She shared two more snaps, one on her own and one with model pal La La Anthony.
The US election will determine the next leader of the free world on November 3.
And the stakes are heightened for Kim this year after husband Kanye West announced his bid for the Oval Office over the summer.
Kim is currently at the heart of controversy for a string of tweets that have been branded “tone deaf” by many, including GMB’s resident firebrand Piers Morgan.
She had penned a lengthy Twitter thread in which she told of how “humbled and blessed” she felt by her luxury birthday celebrations during the pandemic.
Despite the backlash, many others jumped to Kim’s defence.
In the tweets, Kim had told of how she, family and friends had quarantined for two weeks before getting on a private plane to the tropical island.
The trip marks Kim’s 40th birthday, and Kanye is thought to have joined his wife there.
Criticism centred around how people are struggling to cope and have lost loved ones during the Covid.
Alongside a string of snaps from the luxe retreat, Kim gushed about how lucky she felt to be able to get away on holiday with loved ones.
She wrote: “40 and feeling so humbled and blessed. There is not a single day that I take for granted, especially during these times when we are all reminded of the things that truly matter.
“For my birthday this year, I couldn’t think of a better way to spend it than with some of the people who have helped shaped me into the woman I am today.”
“Before COVID, I don’t think any of us truly appreciated what a simple luxury it was to be able to travel and be together with family and friends in a safe environment,” she added.
“After 2 weeks of multiple health screens and asking everyone to quarantine, I surprised my closest inner circle with a trip to a private island where we could pretend things were normal just for a brief moment in time.
“We danced, rode bikes, swam near whales, kayaked, watched a movie on the beach and so much more. I realize that for most people, this is something that is so far out of reach right now, so in moments like these, I am humbly reminded of how privileged my life is. #thisis40.”
In response, Piers retweeted Kim and scolded: “This thread is so repulsive it makes me want to vomit. Not that we needed confirmation but what a spoiled, tone-deaf imbecile.”
