The stars were among five black entertainers recognised for their accomplishments in urban culture at the ceremony hosted by Gabrielle Union and broadcast this week.
According to SOHH, P Diddy, who was honoured for his achievements as a entrepreneur, said in his speech: "I've won a lot of awards before, but I've never been honoured. And being honoured, it feels totally different.
"Especially to be honoured by your people, thank you very much. I'm truly humble, there's a lot of people out there that know my story but there's a lot of people out there that don't. My father was killed when I was three years old so my mother, like millions of black mothers in America, she was a single mother of two raising a family on her own."
Jennifer Hudson, Mary J. Blige and Stevie Wonder also performed at the event, held at the Warner Theatre in Washington DC.
