"I have endless memories of all the years that I have appeared on the American Music Awards", Ross said in a statement.
Daughter Tracee Ellis Ross also hosted the AMAs on ABC, the home of the younger Ross' popular sitcom Black-ish.More news: Selena Gomez Debuts Blonde Hair at AMAs 2017 & We are SHOOK
Throughout her performance, two screens behind her showed a variation of video clips from past shows as well as photos of Ross and her close friends and family. Rhonda Ross's son, Raif (8), and Evan Ross' stepson, Bronx (9), and daughter, Jagger (2), all filed onstage to boogie with grandma.
"This is all about love", Ross said during her brief but joyous acceptance speech. "This is my family and I'm sending love out there to all of you - each and every one of you".
The 2017 American Music Awards aired live Sunday from the Microsoft Theater in Los Angeles. He later closed out the awards show by taking another moment to tell his grandmother that he was proud of her, and to let the crowd know that he loved them too. I really, really love you so very much and I will hold onto this attractive honour.
