Rob Kardashian shares heartbreaking reason he avoids being seen in public

Rob Kardashian has candidly opened up about the heartbreaking reason why he doesn't appear on his families namesake reality TV show and avoids being seen in public.

The 38-year-old was just 20 when a TV crew was invited into his mom Kris Jenner's house, which she shared with her husband at the time Bruce Jenner - now Caitlyn Jenner, and lived there for the first few seasons of Keeping up with the Kardashians.

But while his sisters and mom took to the camera like a duck to water, Rob was more reserved, only appearing on screen a handful of times.

Now, while appearing on his sister Khloé's podcast, titled Khloé in Wonderland, Rob was asked a series of questions by his sister, including whether he finds it 'crazy' that they think the two still live together.

"Not really, we lived together for a long time," he explained.

"I mean, my daughter's always at your house, so..."

Rob continued: "It isn't that crazy... I don't film a lot, so they don't see what, you know, we really do. So it makes sense."

Khloé then asked why he doesn't appear on camera with many people Googling whether there had been a bust up between the Kardashians - to which he shared the heartbreaking reason.

Rob replied: "There's definitely nothing wrong between any of us, it just has everything to do with myself.

"I don't want to be filming and putting myself in a position where I'm not comfortable - like, I'm not comfortable in my skin. So why would I want to go be on camera and just be vulnerable and let like people in when I'm not? That's not what I want to do."

"I mean, that's just how I've been. I'm not going to just put myself out there if I'm not comfortable with myself. I haven't been comfortable with myself in years."

He continued: "And also, filming and doing all that just it's not for everybody. And I choose my own happiness and peace rather than filming for somebody who doesn't do anything for me and my personal life.

"So, that's the truth."

Rob hasn't appeared on The Kardashians yet, although we were offered a glimpse into his life when he was dating Blac Chyna, with the 2016 reality show Rob & Chyna.

They only saw out one season before the pair, who share eight-year-old daughter Dream Kardashian, split up.
