Kim Kardashian and her little brother Rob haven't always had the closest relationship, so when he went through a tough break-up with Rita Ora, Kim's advice to stay out of the media didn't go well. On Sunday night's episode of "Kim & Kourtney Take Miami," Kim talked to an upset Rob on the phone about his recent break-up, telling him to keep it off Twitter.

Rob said that he wanted his fans to know that he wasn't going to step down, and he didn't "want people to think I'm being a bitch." Kim told Rob, "Don't post anything else. Everyone has problems."

After getting off the phone with Rob, Kim calls her mom to talk about their conversation, revealing a nasty email she received from Rob after he asked Kim if Kanye would collaborate on a song with his friend.

Kim told Kris, "He said 'I hope your sex tape haunts you for the rest of your life and I'm going to publicly bash you and Kanye.'"

While Kim and Kanye were out to dinner with Kourtney and her son Mason, Rob called Kim to apologize for his nasty behavior.

Rob said, "I wanted to apologise. Obviously the things I said to you in the text message, I was just being mean," to which Kim replied: "I appreciate you being mature and calling me instead of dragging this fight out."
