Rihanna and A$AP Rocky hold hands as they leave his mom Rina Black‘s book signing event on Saturday (July 13) in New York City.

The 36-year-old Grammy winner and 35-year-old rapper supported Rina at the event, which was hosted by Harlem Honors. Rina published “Harlem Girl 8th Ave (My Truth)” recently.

Here’s a description of the book, from Amazon: “She was a resilient young woman who faced traumatic experiences while growing up in Harlem, New York. Despite the challenges and adversities she encountered, she managed to beat the odds and rise above her circumstances. Her strength, determination, and inner resilience propelled her towards a brighter future, defying the expectations set by her difficult past. She became a symbol of hope and inspiration for others in similar situations, demonstrating that it is possible to overcome even the toughest of circumstances.”
