"I'm frustrated by that decision," Mason Jr. said. "It was a lapse in judgment, it was in poor taste, and it was disrespectful to the creative community — I'm part of the creative community and I know what that feels like, and it's not right."
He also revealed that Haddish was "gracious enough" to speak to him personally so he could apologise on behalf of the Recording Academy.
"I expressed to her my regret and my displeasure about how this went down and how it was handled," he said. "And I will say, Tiffany, we are sorry and thank you for allowing me to speak on it."
The 63rd annual Grammy Awards will take place on January 31. Trevor Noah will host the event.
