While speaking with Bravo's Watch What Happens Live host Andy Cohen, Kim set the record straight on what really happened. She revealed that he didn't tell her he wasn't attending the ceremony until the morning of.

"Yeah, he sent me a long email the morning of [saying] that he was gonna leave, and there was no fight. I just thought, 'this is my day, I'm not even gonna worry about it. I hope he's ok."

Kim Kardashian 'Doesn't Have Sympathy' For Rob Kardashian

Still, while rumor swirl that the brother and sister duo had a huge falling out because of his decision, she made it clear that she understood why he wasn't ready to go to such a high profile event.

"I totally understand that he wouldn't want to see a lot of people if he was feeling uncomfortable. You can only pray and wish that someone would not miss out on more memories in life, because life is about memories, so, fix the problem. We didn't even have a conversation about it."

Even though their sister Khloe Kardashian is extremely supportive of Rob getting his life back on track, Kim opened up about why she prefers to take on the "tough love" method that seems a little more harsh.

"If I don't like something that's going on in my life, I change it. And I don't sit and complain about it for a year. And I'm just a different personality, so I try to encourage him. Once you don't make that change for so long and it's not happening, I get frustrated. My patience runs out."
