Los Angeles, March 16 (IANS): The fact that Rob Kardashian is dating Blac Chyna -- former partner of his step-sister Kylie Jenner's current rumoured boyfriend Tyga -- has had no bearings on the siblings' bond. Both the reality TV personalities are still on good terms.

Rob and Kylie were spotted spending time together and they appeared to be in good spirits, reports aceshowbiz.com. 

The sibling's friend Nicky Diamond uploaded on Snapchat a photograph and a video which indicated that there's nothing wrong between both siblings. 

In the photograph, Kylie is seen standing side by side with Rob as she carried her little puppy; while Rob looked happy as he smiled at the camera and Kylie gave a grin. 

There's also a video which shows Kylie inside a car, as Rob is seen standing next to her. "What's up guys. Hi Kylie," Nicky said as Kylie made a peace sign with her hand, saying "hey" back at him. He then greeted Rob by asking, "What's up bro?"
