The ad had nothing to do with the book, so it gave no further details, but this may have been Mineo's first mention of the book in an interview.
Mineo, who released his latest album, Uncomfortable, in September, also mentioned that he plans on creating more than music in the future.
"Music is just one thing I do," he said, "but I see myself long-term telling stories through visuals and making movies and getting into short films and feature-length films."
Earlier this year, Mineo told Rapzilla that he wanted to film a movie about his friend Raymond Rivera, the founder of Grateful Apparel.
“This guy has so many stories that we need to make a movie about this guy’s life,” Mineo said. “That’s one of the things I want to see done before I’m done.”
Mineo's previous visual-storytelling resume includes three seasons of Saturday Morning Car-Tunez.
