Floyd Mayweather was recently interviewed during a Chicago press conference about his upcoming fight with Marcos Maidana, and a reporter asked about his friendship with Johnny Manziel and Justin Bieber. The woman questioned whether they were real friends or "marketing partners." 

The champion boxer addressed the question by speaking about Johnny's college football achievements, but when it came to Justin, Mayweather hit back hard. He said that the question was "racial profiling," which caught the reporter off guard.
