Chaka Khan expressed disappointment over Clive Davis still throwing his traditional pre-Grammy party the night Houston died and in the same location, at the Beverly Hilton hotel. Houston's body was still in the hotel when celebrities began walking the red carpet to the party.
"I thought that was complete insanity," Khan said on "Piers Morgan Tonight" in an interview that aired on February 13. "Knowing Whitney, I don't believe she would've said the show must go on. She was the kind of woman that would've said, 'Stop everything! Uh uh. I'm not going to be there.'"
Khan, 58, added, "I don't know what could motivate a person to have a party in a building where the person whose life he had influenced so, so enormously and whose life had been affected by her ... They were like ... I don't understand how that party went on."
Houston died at the Beverly Hilton hotel in Beverly Hills, California on Saturday, February 11. The singer was found "underwater" and "apparently unconscious" inside a bathtub in a room on the fourth floor.
The Coroner's Office workers transferred Houston's body out of the building early on February 12.
Houston once covered Khan's song "I'm Every Woman." Khan recorded the song in 1978 but Houston's version became a bigger hit, reaching No. 4 on the Billboard Hot 100 chart, when it was included on the soundtrack for her film debut in "The Bodyguard."
"A true tribute might have been a more honest tribute, in my opinion, would have been, maybe, call everybody together, let's say a prayer and let's eat dinner and go home," Khan told Morgan. "I was supposed to go to the party. I just got off a plane from Miami at about 5:30. As soon as I hit the tarmac, I found out, I heard and I couldn't put on makeup, I couldn't get dressed."
Khan was also scheduled to perform at the tribute for Houston at the Grammy Awards with Jennifer Hudson but dropped out. She Tweeted on February 12, "As I grieve the loss of my friend and 'little sister,' I don't feel it appropriate to perform at this time. Continue to pray for the family."
The singer also took issue with the fact that Houston was in Los Angeles for a week before she was scheduled to perform at the party.
"I too was an addict," Khan told Morgan. "If I was coming to a city like L.A., we'd have made specific plans that I come in night before or day of performance. Especially if you're still -- if you haven't gone into proper treatment and gotten really handled."
"That was the first big mistake, for her to come in an entire week before her performance at the party. I'd never done that," she added. "Whoever flew her out to perform at that party should've provided someone to be there, to somehow just keep the riff raff out of the situation, just keep some of the dangerous people away."
