The New York Daily News reports Mary J. Blige and VH1 producers were reportedly furious when Whitney Houston failed to show up for a rehearsal the day before the Thursday show at the MGM Grand in Las Vegas. An insider revealed, “Everybody was waiting and waiting for Whitney, and she never showed. The VH1 people were pulling their hair out.” Whitney’s rep admits, “She was terribly sorry she missed the rehearsal. She apologized to Mary J.” Blige’s sister Latanya insisted, “Mary wasn’t upset with Whitney. I guess VH1 had some previous problems with Whitney. But Mary knew she was going to show up, and she assured them everything would be okay.” The full article at nydailynews.com has since been removed or relocated.
