"If u were baptised, dress properly," another angry fan wrote.
Then someone else weighed in on the jaw-dropping photo, writing: "Why is she pretending she's the Virgin Mary with a skin-tight dress? She has a full face of makeup and a tight booty showing outfit to get baptized? Yeah ok, Kim. Narcissism at its finest."
Their time away comes after a Kardashian insider claimed Kim and Kourtney have been struggling to get along and continue to butt heads off-screen.
"They can't be in the same room together," a well-placed insider told Radar Online of their strained dynamic. “Kourtney has hated Kim for a couple of years now. She thinks she’s vapid and mean."
“Their egos have clashed big time and when the cameras aren’t on, they don’t speak, “ the source continued. “There are hints of their feud, of course, but the reality is they genuinely can’t stand each other.”
While the source claims Kourtney "has much better things to do with her time than kiss up to Kim," the KKW Beauty founder believes her older sister should appreciate her more, seeing as Kourtney would "be nobody without her".
WATCH: Kim Kardashian calls Kourtney a 'f***ing fake humanitarian ho
Tension reached boiling point between Kim and Kourt last week after the mum-of-four accused Kourtney of being "ungrateful" and "stealing her style".
“Kim and I just got into the biggest fight,” the Poosh founder told her friends during last week's episode. “She just was going so crazy, she’s sending me the meanest text messages. You would die.”
“She’s like, ‘You’re the biggest, ungrateful bitch,’” Kourtney read from her phone. “So I said, ‘God, you’re such a petty woman.’"
Things took a turn for the worse when Kourtney slammed Kim's "terrible attitude".
“You’re going to school to become a lawyer and help the world and these are the kinds of problems you have?” Kourtney said before reading Kim’s response. “Then she’s like ‘You’re really a miserable human-being and you keep not understanding the issue because you all of the sudden turn into such a humanitarian and talk about the world’s issues which you’ve not contributed one ounce to the world.'”
Kim them threw the lowest blow of them all.
“I actually do s**t for the world and you f**king fake it all day long and act like, ‘Oh! There’s people dying, Kim.’ And what the f**k are you doing about it? So, shut the f**k up.”
