Rob Kardashian and his family celebrated Rob's 30th birthday in the suburbs on Friday. Rob's ex, Blac Chyna, joined him and his family that evening but the partying didn't stop there. After celebrating, Blac Chyna had herself a night on the town after Rob's event. The 28-year-old model, who shares a daughter, Dream Kardashian, with Rob, drove 30 miles back into Los Angeles and partied with a group of friends at the Warwick nightclub in Hollywood. Chyna was seen at the venue wearing a tight black top with ripped skinny jeans and a black and white leather jacket.
