Los Angeles, Oct 3 (IANS) Following his break-up with fiancee Blac Chyna, reality TV personality Rob Kardashian is reportedly determined to lose weight and get back in shape. He was working towards getting back in shape and healthy again when he began dating Chyna, but he stopped during the whole break-up episode. According to tmz.com, Rob has hired a nutritionist and started going to the gym. His goal is to get back to the old Rob and he is determined to do it on his own with no help from friends or family, according to the site. As per the report in tmz.com, Rob's friends and family are skeptical that "he can rebound without their help, but they do believe he loves Dream (his daughter) so much that he might have a fighting chance". Rob and Chyna have settled their custody war over daughter. They have agreed to joint custody of their ten-month-old daughter. In fact, Rob has got more than 50 per cent custody. It was also reported that Rob has agreed to pay Chyna $20,000 every month in child support, with Chyna agreeing to drop her domestic violence allegations against him.
