Los Angeles: Reality TV personality Rob Kardashian and his fiancee Blac Chyna are back on good terms again. For the first time since their fight last month, the couple made an appearance together on social media as they had fun with Snapchat's filters during a car ride on Wednesday, reports aceshowbiz.com.  Kardashian appeared on Chyna's Snapchat page sporting his signature black shirt and blue baseball cap as he sat behind the wheel.  "That looks funny, babe, I can't," he said when looking at his own face, while Chyna can be heard giggling next to him.  The "Keeping Up with the Kardashians" star sparked breakup rumours last month after he unfollowed Chyna on Instagram and deleted all their photographs from the photo-sharing site.  A source then revealed that the couple did have an argument, but that wouldn't break them up. In fact, the two started talking to each other again on the following day itself.
