Just two days after celebrating Valentine's Day together, Rob Kardashian and Blac Chyna were seen together in Los Angeles where they stopped at an undisclosed office building. Behind the wheel of her fancy ride, the model sported a black jacket with a NEFF beanie as she dropped off her boyfriend. A source explained that Rob has been "taking better care of himself since his health scare" and Chyna is helping him continue along that path. When Rob pumps iron in the gym, Chyna keeps him company, cheers him on and documents his progress on social media.
