Kim Kardashian shocks fans as she posts bikini picture with 'ride or die' sister Kourtney... hours after Tristan Thompson is caught 'cheating' on heavily pregnant Khloe

Kim Kardashian has come under fire for posting an insensitive bikini picture of herself, sister Kourtney and pal Kristen Crawley. 

The snap was uploaded just hours after their heavily pregnant sister Khloe's boyfriend Tristan Thompson was caught 'cheating' on her. 

While Kim captioned the image of the girls having a blast on holiday in Turks & Caicos, with 'ride or die,' her fans were not impressed.

Followers expressed their disgust at the post in the comments, with one writing: 'They posing for the gram, and Khloe crying in the car.'

While Perez Hilton added: 'How is Khloe doing today?' and another penned: 'Speaking of ride or die. Is Khloe OK today?'

While the girls may have not wanting to wade into Khloe's personal life, the timing of the image seemed a little insensitive given the latest news. 

Tristan spent the weekend hitting up a number of New York City hotspots and holing up in his hotel room with a strip club worker who has been identified as Lani Blair.

The boyfriend of very pregnant reality star Khloe, who is due to give birth any day now, was seen coming and going from his swanky residence for the weekend at the Four Seasons in Manhattan's Financial District with Blair.

They were first spotted kissing at the Penthouse at Dream Downtown on Saturday night, and were later caught on video returning to the Four Seasons in the early morning hours of Sunday.

Khloe has not publicly addressed the news, but the entire Kardashian clan have unfollowed the basketball player on all social media.

While she has also removed him from her feed, Khloe is yet to delete pictures of the couple together from her account. 

Meanwhile Kim and Kourtney were enjoying their holiday in Turks and Caicos when the news emerged - having shared a number of sizzling snaps from the break over the last week. 

Kim flaunted her curves in a thong bikini as Kourtney, 38, posed in an equally revealing look for an Instagram photo, shared on Tuesday. 

Kim, who wrote the caption '#NationalSiblingDay,' donned a low-cut sports bra style bikini top with thong bottoms.

She kept her makeup to her minimum while posing on the rock besides her older sister in a yellow and black visor.

Kourtney flaunted her flat stomach as well in her barely there swimwear with a matching visor. 

On Tuesday, Kim had already wowed in her hot pink Chanel bikini, which barely covered her physique.
