Seems Blac Chyna and her on-off fiance Rob Kardashian are back together again. Chyna shared some snapchat videos where she can be seen wriggling her waist as Rob cuddles her from behind. Chyna later asked Rob to give her a kiss and he obliged by kissing her on the cheek. Only few days ago, Chyna 28, lashed out on her page after she felt that her two baby daddies Tyga and Rob are team tagging her. She even called out Tyga for skipping child support.
