Khloe Kardashian Talks Reclusive Brother Rob, How She's Helping

"He's only wasting his life more and more," she said.

In an interview with People magazine, the reality star said her little brother, 28, "is such a great guy. He's charming, charismatic, everything. That's what's so infuriating. I'm like, 'Where is your will to live life? Let's be around people.’"

Rob has been out of the public eye for almost a year and a half now. Indeed, he lives with Khloe, 31, who says she has "been working on my patience" in helping him deal with weight issues and more.

"But I have my moments and I do snap. I've offered to get a chef. I'm like, 'What's your excuse?' But it's not just that. I can't win life for Rob. I have to wait until [he's] ready to do it for himself," she added.
