Kylie Jenner's Instagram tribute for her sister, Khloe Kardashian, was reportedly meant to diss their mother, Kris Jenner. According to a report from Radar Online, the "Keeping Up with the Kardashians" star is being fake with their family "momager."

"Kris has been properly put in her place by Kylie and she is extremely upset over it," a source revealed.

Kylie Jenner's Instagram post last Mother's Day featured a collage of images of her and Khloe Kardashian.

"Don't forget about your first daughter when you decide to start your own family," she wrote across the montage.

The caption of Kylie Jenner's Instagram tribute spoke about how she considers her 30-year-old sister as her "mother figure." The sisters' closeness are evident in their reality series "Keeping Up with the Kardashians."

"Thank you for being you (and for) being another mother figure to me my whole life and doing the same for our nieces and nephews," Kylie Jenner wrote alongside her post for Khloe Kardashian.

The said tribute was posted by the 17-year-old reality star soon after she uploaded photo of her gift to Kris Jenner. She and her sister, Kendall Jenner, gave their "momager" an extravagant balloon display that was set up at the grand entrance of her house where most episodes of "Keeping Up with the Kardashians" are filmed.

However, the infamous "momager" was allegedly not pleased with her daughters' Mother's Day gift.

"Kris feels that the girls present to her was just about as fabricated and generic as it could possibly be," an insider claimed.

"Kendall and Kylie came up with the idea to do this because they knew that Kris would post it on her social media right away, making it look like they actually give a d**n!"

"They wanted to do something for their mom that was over the top like she is and this was the best thing that they could come up with," the insider added.

"But instead of a heartfelt message to Kris, Kylie chose to wish Khloe a Happy Mother's Day because she was more of a mom to her than Kris ever was," the source further explained.
