On Sunday night, the life and impressive career of Whitney Houston were celebrated at the 2012 Grammy Awards, with everyone from Bruno Mars to host LL Cool J and Jennifer Hudson recalling the immense talent of the late icon.

Since her passing on Saturday, more reports have surfaced about what might have contributed to her death. After initial speculation that she might have drowned in the bathtub of her Beverly Hills hotel room, a new TMZ report suggests that prescription drugs and alcohol might have played a bigger part in her death than originally believed. Sources tell the site that L.A. County Coroner's officials have told Houston's family that despite earlier drowning reports, it's likely she died of a combination of Xanax, other prescription drugs and alcohol. There wasn't enough water in her lungs to suggest that drowning played a part, the report says, and she might have died before her head was submerged in water. Her body was reportedly found by her aunt, Mary Jones, who entered the bathroom to check on the singer. Houston's body will be flown to Atlanta once it is released from the coroner's office, sources said. Meanwhile, Houston's daughter, Bobbi Kristina, has been released from Cedars-Sinai Medical Center after being treated for a stressed-induced panic attack shortly after her mother's death. Since Houston's passing, Bobbi Kristina's father, Bobby Brown, has flown to L.A. to be with his daughter, E! News reports. According to a People.com eyewitness, when he landed in L.A., "Bobby had a blank stare and looked exhausted ... His friends seemed concerned about him and they surrounded him as they walked through the airport." He had been on tour with New Edition when he left the trek to join Bobbi Kristina. Sunday's hospitalization allegedly wasn't the only health scare for the 18-year-old over Grammy weekend. TMZ reports that she had fallen asleep in the bathtub Friday at the same hotel where her mother was found dead the next day. Bobbi Kristina's friends reportedly called security to unlock the door and help them remove her from the tub.
