Blac Chyna will officially be Angela Kardashian in 2017. The reality star just announced her wedding date with Rob, and it will happen on July 17, according to In Touch Magazine. “The number seven is Rob’s lucky number, and he’s extremely superstitious, so picking a date was very important to him,” a source told the mag. He also was looking at his birthday, March 17, but Chyna didn’t think her post-baby snap back would be perfect by then.
