The three acts performed a medley of the late Ruff Ryders superstar's biggest hits, including "Get at Me Dog", "Hood Blues", and "Where the Hood At?" before actor Michael K. Williams appeared in a trademark DMX look and performed a medley of DMX classics.
Busta Rhymes was also part of the fun as he led a rendition of the rapper's 2000 hit "Party Up (Up in Here)".
DMX died in April (21) at the age of 50 after suffering a heart attack.
Another emotional moment at BET Awards was when Queen Latifah collected Lifetime Achievement honour.
Holding back tears, the rap pioneer and actress took the stage after Lil' Kim, Rapsody, MC Lyte, and Monie Love delivered a stirring tribute, and had to compose herself before accepting the honour.
"I'm so extremely moved I don't even know what to...," she said. "I want to thank BET for creating an outlet for beautiful blackness to thrive, to shine. When we couldn't get played on the radio and other places, we couldn't get our videos played in other places, there was BET that allowed us to be in our fullness."
Latifah also thanked God, her father, who joined her onstage, and her late mother, stating, "I've always celebrated the woman because I was raised by a strong Black woman, and raised by a father who loves women."
She also gave longtime business partner Shakim Compere a big shout-out, adding, "Thank you for always protecting me and loving me... You and your family are my family."
