Diddy railed on the Grammys Saturday, saying it's turned a blind eye to black artists ... notably, hip-hop artists.
Ironically, Diddy unloaded on the Grammys during his acceptance speech for receiving an Industry Icon award. It all went down at Clive Davis' pre-Grammy gala at the Beverly Hilton Hotel.
As you know, TMZ broke the story ... Whitney Houston died the evening of the same annual party back in 2012 when she was found in her bathtub at the Beverly Hilton, dead from an OD.
As for Diddy, he gave an acceptance speech that was interminably long -- 50 minutes, seriously. It ended at 12:30 AM, and toward the end is when Diddy set his sights on the folks who run the Grammys.
Among many other things ... Diddy said, "Truth be told, hip-hop has never been respected by the Grammys. Black music has never been respected by the Grammys."
As for Diddy's record ... 3 Grammy wins and 13 noms.
Among the guests ... Speaker of the House Nancy Pelosi, Cardi B and Offset and Lana Del Rey, John Legend, Janet Jackson, Faith Evans, Ma$e, Lil Kim, Ozzy Osbourne, Avril Lavigne, Paula Abdul, Trevor Noah, Billy Porter, Darren Criss, Jessie J and Channing Tatum.
