Kim Kardashian has revealed her brother Rob Kardashian fled Europe and bailed on her wedding without even telling her face-to face — he just sent an email!

The reality TV star finally addressed rumors surrounding Rob's shock departure from Paris during a revealing interview on Watch What Happens Live on Tuesday, Aug. 12.

When asked by host Andy Cohen whether the two had reconciled following their wedding fight, the 33-year-old mom of one replied, "He sent me a long email the morning of that he was going to leave. There was no fight."

"I just thought, 'You know what, this is my day, I'm not even going to worry about it,'" continued Kim. "I totally understand that he wouldn't want to see a lot of people if he was feeling uncomfortable and you can only pray and wish that someone would not miss out on more memories in life, because life is about memories."

Earlier in the show, Kim insisted she wasn't "non-empathetic" over Rob's issues, and loves her brother very much.

"My brother and I are so close, he's one of my best friends," she insisted. "I'm definitely a tough love kind of person. 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.”

The reality star admitted that she can get frustrated with Rob for not doing enough to make a difference in his own life. "I try to encourage him,” she said. “And once you don't make that change for so long, and it's not happening, I get frustrated. My patience runs out," she explained.
