How can you tell that rapper Tyga is black?
Easy, just read the story about his "about to go public" romance with Bruce Jenner's daughter.
What's your clue? Well, if you're stumped I'll show you the relevent passage: emphasis mine.
The pair is said to have started dating last year, following Tyga's split from his baby's mother, Blac Chyna, but they have continued to play coy over the status of their relationship, despite frequently being photographed together.
