As we reported last night, Whitney Houston passed away in Beverly Hills on Saturday at the Beverly Hilton. She was 48 years old. She passed away during Grammy Weekend – where musicians, pop stars, rap and hip-hop stars and everyone and anyone involved in the music industry descends on LA for pre-Grammy parties and the actual Grammys, which are still scheduled for tonight. Ever since Whitney’s rep confirmed Whitney’s death, there has been a rush of information. Here are some bullet points:

*Whitney was discovered by a member of her entourage, likely a bodyguard. The person called hotel security, who in turn called 911. Whitney was unresponsive (likely already dead) when the EMTs arrived. TMZ’s sources claim that the night before her death (Friday), Whitney “partied heavily” at the hotel, “drinking and chatting loudly with friends in the bar.” Both Whitney’s mother (Cissy) and her cousin (Dionne Warwick) spoke to Whitney just hours before her death, and they both say she sounded fine.

*Whitney’s daughter Bobbi Kristina “got into an angry shouting match with police officers outside the hotel room where her mother was found dead.” Hours after Whitney’s death, Bobbie Kristina tried to see her mother’s body, but she was told no one was allowed in. Dionne Warwick was also sent away.

*The LAPD’s initial assessment is that there is no foul play. TMZ’s sources (probably inside the LAPD) claim that “no illegal drugs have been found in the hotel room where Whitney Houston died” but they’ve found prescription drugs. Allegedly, Whitney was found in the bathtub, and EMTs removed her from the tub, and there are suspicions Whitney might have passed out and drowned. There’s also a theory that she simply overdosed. Allegedly, no alcohol was found in the room either.

*TMZ says Whitney was taking Xanax. Xanax mixed with alcohol = not good. But! Radar says the LAPD found “a plethora of sedatives including Lorazepam, Valium, Xanax, and a sleeping medication that was found in her hotel room.” The autopsy will take place today or tomorrow, and the assumption (by Radar’s sources) is that Whitney accidentally overdosed.

*Whitney’s last film, Sparkle, is still scheduled to be released later this year. Sparkle is a remake of a 1976 film about young musicians struggling with addiction. Whitney had bought the rights to the story a decade ago, she executive produced the remake, and she costars as the mother of Jordin Sparks’ character. The last time Whitney was in a film was in 1996, in The Preacher’s Wife.

*Listen to the isolated vocals of Whitney singing “How Will I Know” here.

*Tony Bennett is using Whitney’s death to campaign for the legalization of drugs. His argument is lacking.

*Whitney’s last interview was with Access Hollywood? You can see it here.

*Read some statements from celebrities who loved Whitney here and here.

*Grammy producers are scrambling to add last-minute tributes to Whitney during tonight’s broadcast. Jennifer Hudson is coming on to perform “a respectful musical tribute” to Whitney. Allegedly, Chaka Khan might join her. My guess is that some of Lady Gaga’s performance time is being cut to make room for Whitney’s tribute.

*Bobby Brown cried during a concert last night.

RIP Whitney, you will be deeply missed.
