Rob Kardashian has been noticeably struggling for quite some time now. His sister, Khloe, was in Las Vegas this weekend for a paid appearance at the Mirage Hotel’s 1OAK when she spoke with Wonderwall about her younger sibling’s personal life.

"I just feel, especially over the last year, Rob has become very introverted and has a kind of social anxiety, " the Keeping Up With The Kardashians star claimed.

"He's definitely not at his happiest place that he once was, and I know he can get to that happy place and he will."

Kardashian has been fighting weight issues for a couple of years now, and with a family whose job is to look good, that can't be easy. He's rarely photographed outside his house, likely due to the fact that barely leaves home.

"We all kind of get to a place where you don't know where to go in life or whatever, so I think it's important for him to know that he always has people to lean on and it's not unnatural for people to not know even where to begin. It's a growing process," his sister vouched.

If there's one thing Rob can focus on, it's that his older sister always has his back.

"I will always be his No. 1 supporter."

Get well soon, Rob.
