‘He has no loyalty’: Kim and Khloé get to grips with Rob’s relationship

There's definitely been no shortage of excitement since the Kardashian family hit our screens way back in 2007, but the latest dramatic storyline to unfold within the Calabasas clan is definitely one of the more compelling.

With Rob beginning a relationship with the ex-girlfriend of his younger sister Kylie's current boyfriend, tensions within the infamous reality television family were running high, but it looks like Rob's siblings are somewhat torn over the turn of events.

Having spent the last few years hiding from the media, Rob, who is due to become a dad in the not-too-distant future, has done a full 180, and with the help of new bae, Blac Chyna, is slowly getting to grips with day to day life in the spotlight.

Discussing their brother's remarkable turnabout in the latest KUWTK episode, Kim and Khloé could be seen praising Chyna for her part in Rob's happiness, but insisted their brother had no loyalty.

"My thing is, do what you want, do what makes you happy. But he should have said to us, 'Hey guys, this is how I feel, I can't help who I love," Kim told her sister.. "Kylie should know this. He just has no loyalty."
