She may have come to his defense Tuesday when his ex-girlfriend Adrienne Bailon aired out their relationship during a recent interview, but Kim Kardashian and her brother Rob Kardashian are reportedly still not communicating with each other.

The siblings' spat reportedly began ahead of Kim’s nuptials to Kanye West on May 23. On the morning of the wedding in Florence, Rob flew back to Los Angeles, skipping out on his sister’s big day. Sources at the time told Radar Online that he ditched the wedding due to a fight he had with Kim just hours before.

In the days following the wedding, Rob, 27, cleared his entire Twitter account and was said to have also cut off all communication with both his sisters Kim, 33 and Khloe Kardashian, 32. And though it’s been months since their initial falling out, a source speaking to Hollywood Life says Kim and Rob have failed to resolve their problems.

“Rob says Kim has not reached out to him once since the wedding and they are still at odds with each other. He hasn’t reached out to her either,” the family friend said. “Kim thinks Rob owes her a major apology and Rob thinks Kim doesn’t care about him. Rob resents that Kim has never taken him or his feelings seriously.” 

It remains unclear if Rob has patched up his problems with Khloe. But the source added that she doesn’t approve the tactics that Kim uses in her attempt to help their brother.

“Khloe gets him and understands that he’s always been very sensitive, he’s a Pisces. But whenever Khloe says that, Kim laughs at her and makes light of the situation. She just thinks it’s mind over matter and doesn’t think he’s really depressed, more so that he’s selfish and stubborn,” the source said. “This is the main reason Kim and Khloe argue — over Rob. Khloe thinks Kim’s insensitive and Kim thinks Khloe is overprotective.”

No matter their personal issues, though, the sisters rallied behind their brother after his ex-girlfriend Adrienne Bailon dissed him in the September 2014 issue of Latina magazine. In the magazine, Bailon, 30, says she is tired of people giving her a  hard time for breaking up with Rob, and that she regrets appearing on “Keeping Up with the Kardashians."

In response to her loaded comments, Kim and Khloe took to Twitter to blast the actress and let her know they don’t appreciate her speaking bad about their family or their brother.

Rob has remained out of the spotlight for the last few months, with his family and fans remaining concerned about his physical and mental health. He was recently photographed in Malibu as he spent the weekend with several of his friends. The images sparked talk that the “KUWTK” star may have gained more weight over the last couple months.
