Khloe Kardashian set the record straight about her relationship with Rob Kardashian.

On Friday, the 34-year-old posted a photo of her mother, Kris Jenner, along with a message of gratitude. Kardashian thanked her mom for raising "multiple mini queens."

"You are a Queen who has raised multiple mini Queens still trying to be as strong and fabulous as you are!" she wrote. "I will love you more and more every day until the end of time."

The caption prompted a strange response from fans, who felt Kardashian was leaving brother Rob Kardashian out -- perhaps intentionally. Khloe was accused of "forgetting" about her brother.

'It's a shame Rob Kardashian is a member of the family and he is NEVER mentioned," one Instagram user wrote.

Khloe replied, "My brother is my entire world! He is definitely a king. It is a shame that you can [SIC] respect us for respecting his privacy. You should not comment if you truly aren't informed on our family."

She also responded to another fan who commented, "Don't forget about Rob. She's raising a king too."

"He has always been a king since the minute he was born! My mom and dad did an amazing job with him. He is my <3."

While Khloe hasn't been overly public about what's going on with Rob, 31, she did recently stay with him. The Keeping Up With the Kardashians star and her daughter, True, stayed at her brother's house when she was forced to evacuate during the California wildfires.

Rumors began swirling about Rob recently, suggesting that he's "turned his life around," according to ET Online. He's said to have been working with a trainer and feeling better than he has in years after being told his weight could be life threatening.

"Rob has struggled nonstop for years with his weight and he finally seems to have turned his life around," an insider said. "Lately Rob's friends have been talking about how proud they are of him because he made his health a priority."

The source added, "He was warned that if he didn't lose weight, it could eventually become life or death, but since then he lost pounds and feels so much better. He works out regularly with a trainer and that has made a difference in his shape. He really is beginning to look like the old Rob."

Rob is said to have lost between 30 and 50 pounds.
