• Khloé shared a throwback photo of herself, boyfriend Tristan Thompson, Kim, and Kanye
  • She called the "Gold Digger" rapper her "brother for life"
  • Khloé slammed the troll and defended herself and Kim over the birthday message

Khloé Kardashian clapped back at an Instagram user who lambasted her and sister Kim Kardashian for wishing Kanye West on his 44th birthday amid his impending divorce from the beauty mogul.

The “Keeping Up with The Kardashian” star wrote a sweet birthday message for Kanye on Instagram on Tuesday along with a throwback group photo of Kim, Kanye, and herself with her boyfriend Tristan Thompson posing in the ocean.

"Happy birthday to my brother for life!!!" Khloé wrote in the caption. "Have the best birthday Ye! Sending you love and endless blessings!!” she further stated.

Kim, who filed for divorce from Kanye in February, commented on her sister’s post with a red balloon emoji. However, the KKW Beauty founder’s comment irked one user who criticized her and Khloé for honoring the “Gold Digger” rapper 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 Instagram user wrote, as reported by People. "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 (sic)."

Khloé retorted to the user, defending herself and Kim’s decision to write a heartfelt birthday message for the “Flashing Lights” hitmaker.

"Why are you even commenting on something you know nothing about?" she said. "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," Khloé continued. "Not yours! Don't comment as if you in the know unless you are actually in the know. Weirdo!!"

Kim and Kanye started dating in 2012 and tied the knot in 2014. They have four children -- Psalm, Saint, Chicago, and North, together.

Sources have claimed that Kim and Kanye are in agreement over joint legal and physical custody of their kids, and neither of them is contesting the prenup in place, TMZ reported. Negotiations have, reportedly, progressed and the two are nearing a settlement.
