Whitney Houston's Final Days

While the cause of her death is still unclear, details emerge about how the pop legend spent her last few days.

The circumstances behind Whitney Houston's death are still murky, but details about the legendary singer's final 72 hours provide a conflicting view of how she spent her last days. Houston died on Saturday at the age of 48, with the most recent reports suggesting that she may have succumbed to a combination of prescription drugs and alcohol, and not as a result of drowning in her hotel bathtub as initially thought.

Houston had kept a relatively low profile recently, emerging sporadically in late 2011 to promote her role in the upcoming film, "Sparkle," in which she plays singer Jordin Sparks' mother.

The remake of a 1976 film about talented young musicians struggling with addiction — a story Houston was sadly familiar with in her own life — is slated for release in August. It was Houston's first major film role in 16 years and was to be a precursor to her expected role in "Waiting to Exhale 2."

As investigators try to piece together what killed the singer, a clearer picture is emerging of how Houston spent her final days.

February 7: According to TMZ, Houston paid the second of two recent visits to a Beverly Hills doctor, though it has not yet been determined what kind of physician she saw.

February 9: Houston dropped in on a pre-Grammys party in support of her old friend and R&B singer Kelly Price, who told MTV News her old pal seemed just fine. "We were talking about the kids, she was telling me how proud of me she was for doing this record, doing it independently ... and singing the truth," said Price, dismissing rumors that Whitney was partying heavily that night. "I was still at my hotel getting my hair curled and they called me and said, 'Whitney's there!' She beat me to my own party," said Price, who performed a gospel duet with Houston that night in what turned out to be Whitney's final stage appearance.

"She strolled down the red carpet, she smiled, she interviewed. She went down to the VIP area and she waited for me. ... My friend has had some troubles and challenges down throughout the years, but you have to judge a moment by the moment. You can't just automatically assume that something else happened. ... She was happy that night."

February 10: Though she had no official appearances on the day before her death, witnesses told TMZ that the singer had "partied heavily" with friends at the Beverly Hilton Hotel that night. The boisterous group reportedly drew stares at the hotel bar packed with other Grammy revelers. The site also claimed that Bobbi Kristina, Houston's 18-year-old daughter with Bobby Brown, allegedly fell asleep in a bathtub in the same hotel less than 24 hours before her mother's demise.

February 11: Hours before she was reportedly scheduled to attend mentor Clive Davis' annual pre-Grammy bash, news broke that Houston was found dead in the bathtub of her Beverly Hilton Hotel room by members of her staff. CPR was attempted and did not work, and the 48-year-old singer was pronounced dead at 3:55 p.m. Police found no evidence of foul play and are currently awaiting toxicology reports.

February 12: LL Cool J leads a night of tributes to Houston at the 54th annual Grammy Awards, culminating in a stirring rendition of Whitney's signature cover song, "I Will Always Love You," by Jennifer Hudson.

February 13: TMZ posts a report containing photos of what they claim are the room-service trays ordered by Houston just before her death. They show several meals, as well as a Heineken can and an empty champagne glass, which suggests that she may have had several drinks on top of whatever prescription drugs she ingested before getting into the bathtub. (There is no proof, though, from the pictures that Houston alone consumed the drinks.)
