Died at the age of 48 in Los Angeles on Feb. 11, 2012.
The morning after Clive Davis' Grammy party turned into a celebratory tribute, details surrounding the death of Whitney Houston began to emerge.
The singer was found unconscious and submerged in the bathtub of her room at the Beverly Hilton by her hairdresser Saturday afternoon, according to TMZ. She called security, paramedics were summoned and a bodyguard attempted to resuscitate her via CPR, but Houston was declared dead at 3:55 p.m.
Coroner's officials say they will not release any information on Whitney Houston's autopsy at the request of police detectives investigating the singer's death.
Capt. John Kades says an autopsy on Houston was schedule Sunday but that a security hold prevents him from releasing any details on its status or whether any probable cause of death has been established.
Beverly Hills Police Lt. Mark Rosen said Sunday that his agency may release more details about Houston's death Saturday afternoon on Monday, but it will depend on whether detectives feel comfortable releasing any information.
The singer's death, coming on the eve of Sunday night's Grammy Awards, threw organizers and those in town for the event into a state of shocked disarray.
Even as planners worked to incorporate a tribute to Houston into Sunday night's events, Recording Academy CEO Neil Portnow said "a light has been dimmed in our music community today, and we extend our deepest condolences to her family, friends, fans and all who have been touched by her beautiful voice."
In her career, Houston sold over 170 million albums and singles worldwide, with many hit singles. Her lead single, "I Will Always Love You," became the best-selling album by a female artist in music history.
She was the only artist to chart seven consecutive No. 1 Billboard Hot 100 hits: "Saving All My Love for You," "How Will I Know," "Greatest Love of All," "I Wanna Dance with Somebody (Who Loves Me)," "Didn't We Almost Have It All," "So Emotional," and "Where Do Broken Hearts Go".
In what appears to have been her last public appearance, Houston attended the Kelly Price & Friends for the love of R& B event at Tru Hollywood on Thursday night.
She arrived with her daughter Bobbi Kristina and walked the red carpet. She took the stage to sing a brief duet of "Jesus Loves Me" before returning to her table. She left with her entourage after the performances.
