Singer Kelly Price told CNN on Monday that she performed an impromptu duet with Whitney Houston at a party two days before Houston's death.
"She did not seem disheveled. She was dancing, she was laughing. ... We were having a good time," said Price said of the party two days before the Grammys. "What I saw on Thursday night was not erratic behavior. I didn't see someone who was high."
Friend: Whitney was 'joyful and upbeat'
Beverly Hills police have requested a "security hold" on the coroner's report, a common practice in high-profile cases that limits what can be revealed about a probe while it is ongoing.
Speaking to reporters Monday, Ed Winter, assistant chief of the Los Angeles county coroner's office, refused to speculate on a cause of death, saying testing is ongoing. Winter on Sunday said no additional details, including what was discovered in Whitney Houston's room, would be released.
Speaking to Rolling Stone, singer Tony Bennett, who won two Grammys Sunday night, recalled to Rolling Stone the first time he heard Houston's voice. "I called Clive Davis up," he said of the record label boss who discovered Houston. "And I said, 'Clive, that's the best singer I ever heard in my life. You really got something on your hands.' Sure enough, at the beginning she was singing everything so beautiful.
A source close to Houston, however, told CNN Monday that her body will be flown to her native New Jersey, and a funeral service will be held there Friday or Saturday.
Whitney Houston's music skyrocketed to the top of the charts in the wake of the singer's death, which was announced on Saturday.
Houston's recordings ruled the top 175 songs on Apple's iTunes on Monday, led by her recording of the Dolly Parton song, "I Will Always Love You."
"I Wanna Dance with Somebody" and "Greatest Love of All," both from Houston's "The Greatest Hits" album, clocked in at numbers two and three.
Tributes continue to pour in Monday while questions remain in the wake of pop diva Whitney Houston's sudden death, which loomed over the music world's biggest stage this weekend, the Grammys.
Coroners on Sunday completed an autopsy on Houston, who was found dead Saturday in her suite in the upscale Beverly Hilton hours before she was to attend a pre-Grammy Awards bash at the hotel.
Assistant Chief Ed Winter of the Los Angeles County coroner's office told reporters "there will be no cause of death at this time because it is pending toxicology reports." Those lab results are expected in six to eight weeks.
On Sunday night, the Grammy Awards feted a new siren, Adele, even as it mourned a classic one, with celebrities paying tribute to Houston on the star-studded night.
Host LL Cool J opened with a prayer for Houston, a six-time Grammy winner. "How do we speak to this time, to this day? There is no way around this. We've had a death in our family. At least to me, the only thing that seems right is to begin with a prayer for the woman that we loved, for our fallen sister, Whitney Houston." The crowd paused as the rapper and actor said a quick prayer.
Earlier Sunday, Houston's 18-year-old daughter, Bobbi Kristina, was taken to a Los Angeles hospital, police said.
Beverly Hills police said Sunday the teen went to Cedars-Sinai Medical Center at about 11:15 a.m. She was released later Sunday and was expected to head to New Jersey, where her grandmother lives, said a source close to the family.
Singer Kim Burrell, a family friend, told CNN she was with the teenager Saturday at the Beverly Hilton after Houston died. "As to be expected, she's overwhelmed – it's her mother. She knows how much her mother meant to the world. And Bobbi Kristina has a huge heart, just like her mother," Burrell said from the red carpet at the Grammys.
