But the Skims founder’s comment struck a nerve with one user, who tagged Kim in a comment, criticizing both her and Khloé for honoring West’s birthday in light of the ongoing divorce.

“@Kimkardashian. Im sorry Kim. The whole ‘brother for life ' thing is too petty for me. Your sister bond should be much more strong than feeling the need to say that,” the user argued. “Your divorce was so hard on you even the picture is just uncalled for. There is so many other pictures. Google could of been her friend. This wasnt cute but Im glad your being strong through it all.”

Khloé responded back to the user and defended herself and her older sister’s decision to share posts for West’s birthday.

“Why are you even commenting on something you know nothing about?” she asked. “You don’t think me and my sister’s talk about one another’s feelings? We are with one another every day.”

“This is MY FAMILY,” she continued. “Not yours! Don’t comment as if you in the know unless you are actually in the know. Weirdo!!”

West’s birthday came nearly four months after Kimfiled for divorcefrom the artist, with whom she shares daughtersNorth, 7½, andChicago, 3, and sonsSaint, 5, andPsalm, 2.

On Tuesday, the reality star alsocelebrated her ex’s birthdaywith an Instagram tribute of her own, posting a photo of the former couple alongside their threeeldest children.

“Happy Birthday Love U for Life! 🎈” Kim captioned the old family photo.

And while it wasn’t an easy step to take,a source recently told PEOPLEthat Kim is at peace with her choice and is “doing great.”

“Kim is doing great,” the source said. “She was really struggling around the time she filed for divorce. She was very upset about it and really didn’t want to file. She has come a long way since she filed for divorce, though. She’s very happy and convinced that she made the right decision.”

In addition, the source added that the pair’s children “are doing well,” and that West sees them “often.”
