According to reports by TMZ, bottles of prescription drugs were found in the Beverly Hills Hilton hotel room where Whitney Houston’s lifeless body was discovered Saturday afternoon just hours before a huge Grammy party she was to attend, a report says.

Police discovered “various pill bottles” in Houston’s room, TMZ reported, adding that family members said Houston had been taking the prescription drug Xanax, which is often used to treat anxiety.

No alcohol was found in the preliminary sweep of Houston’s room, TMZ reports, but there were multiple reports that Houston had been drinking with friends the night before at the hotel.

Houston had also attended rehearsals for the Grammys on Thursday, coaching singers Brandy and Monica, according to a person who was at the event but was not authorized to speak publicly about it. The person said Houston looked disheveled, was sweating profusely and liquor and cigarettes could be smelled on her breath.

She was also observed behaving “erratically” earlier in the week at a Los Angeles club, according to multiple reports.

Houston’s body was removed from the hotel early Sunday morning ,hours after the Grammy awards party she was there to attend had taken place four floors below her room. Her body was taken to the L.A. County coroner’s office, where an autopsy will be performed to determine her cause of death.

Houston was 48.

Houston’s death on the eve of the Grammy Awards sent shock waves through the music industry, with many stars expressing shock and sadness.

Brown reportedly broke down backstage before a show with his band New Edition in Southhaven, a few miles south of Memphis.

Brown skipped the first song of the concert, but appeared onstage for the second. He shouted, “I love you, Whitney. The hardest thing for me to do is to come on this stage.” He then blew a kiss to the sky with visibly teary eyes. It surprised many observers that he took the stage at all.

Aretha Franklin, her godmother, issued a short statement: “I just can’t talk about it now. It’s so stunning and unbelievable. I couldn’t believe what I was reading coming across the TV screen.”

Houston’s death will likely put a damper on Sunday’s Grammy awards, music’s biggest night of the year. Jennifer Hudson and Chaka Khan will perform a tribute to Houston at the awards, according to reports.

Grammy executive producer Ken Erhlich said event organizers believed Hudson — an Academy Award-winning actress and Grammy Award-winning artist — could perform a “respectful musical tribute” to Houston, the Los Angeles Times reported.

British Celebrity Reporter Nigel Pandomonium, an IC columnist and regular contributor said “Gertrude and I are stunned and saddened by this shocking news. With the Grammys here, I do not know what they will do. I have called Ken to see if there is anything I can do in this crunch to assist him as I know he is over the coals with this thing.”

“It’s too fresh in everyone’s memory to do more at this time, but we would be remiss if we didn’t recognize Whitney’s remarkable contribution to music fans in general, and, in particular, her close ties with the Grammy telecast and her Grammy wins and nominations over the years,” Ehrlich told the newspaper.
