Hollywood Life reports that Kim Kardashian is certainly hoping for an apology from her brother who unexpectedly skipped the wedding. "Kim says Rob owes her a major apology," a source told the Web site. But she demands more than a simple "I'm sorry" from him.

The source reveals that Kim Kardashian believes that he must bring a change in his attitude and that "his weight issue is not his only problem."

"Keeping Up With the Kardashians" (KUWTK) star also feels that her brother needs "professional help to deal with his pent-up rage and buried emotions."

"Kim, along with the rest of the family, has been urging him to go to therapy for quite some time now and his answer is always the same - 'I don't believe in therapy.' I mean even if he loses the weight, he's still going to have the same issues."

Furthermore, Kim Kardashian is also looking forward to a confrontation with Rob Kardashian. VH1's The Gossip Table (via She Knows) suggests that the first thing she wants to do, now that she is back from honeymoon, is meet up with Rob Kardashian and ask him some questions. It is said that is "not going to be a happy reunion."

Meanwhile, latest reports claim that Rob has unfollowed most of his family members on Twitter. Except Kylie Jenner and his mother Kris Jenner, Rob has excluded everyone else from his list of friends on micro-blogging Web site.

In addition to that he has decided to quit his family reality show "Keeping Up With the Kardashians" (KUWTK), according to Radar Online. He also believes that this reality show has "ruined" his family.

Meanwhile, citing In Touch Weekly's claims, Celebrity Dirty Laundry reports that Rob Kardashian has a plan to get back at his family. He is reportedly "threatening" his family to expose their "deepest, darkest, craziest secrets" to the world. And he plans to do it by the means of a new tell-all that he will pen down.

The magazine claims that Rob Kardashian's tell-all will consist of secrets like number of plastic surgeries Kim Kardashian underwent and a sex tape that could allegedly "destroy" the Kardashians. In addition, it will also talk about Scott Disick's affair with other women and reveal Khloe Kardashian's real father's name. If this report is to be believed, then Rob Kardashian's writing debut is going to be pretty interesting with juicy behind-the-camera information which is going to annoy pretty much everyone especially Khloe and Kim Kardashian.
