Reports say that Whitney Houston had a mixture of Valium, Xanax and alcohol in her system when she died at the Beverly Hilton on February 11th. According to RadarOnline.com, a source said, "The coroner is waiting on final toxicology results to determine which one of the three was the major contributing factor of her demise. The coroner will be closely examining Whitney's blood alcohol content at the time she died as well. The sedatives and alcohol will almost certainly be the cause of death, and not drowning."

The source continued, "Her heart stopped beating because her respiratory system was suppressed because of the anti-anxiety meds, and combined with the booze it probably happened very quickly before she was found partially submerged in the bathtub."

The final toxicology results for Houston should be released in the next several weeks.

REPORT: WHITNEY HOUSTON WAS WORKING ON BIOPIC BEFORE HER DEATH

In other Whitney news, according to E! News, the pop icon was beginning talks about developing her biopic shortly before her death. Actress Meagan Good -- who previously said that her dream role was to play Whitney, said that she and the pop icon were in talks.

She explained, "We were fairly in the beginning stages. We were supposed to meet today actually. My feeling is because she has the film Sparkle coming out and she's brilliant in it and she looks beautiful and healthy, my feeling was that's how we should end the movie - as a new beginning for her."

Meagan said it is too soon after Whitney's death to think about the future of the film. She added that she would never attempt to do her own singing.

IS BOBBY BROWN TO RELEASE TELL-ALL BOOK?

Is Bobby Brown planning to release a tell-all book about his life with ex-wife Whitney. According to E! Online, a major publisher said, "Back in 2008, the interest in a book on Whitney Houston wasn't that great. Whitney had fallen off the radar back then ... but now, following her tragic death, the market has changed. Now is the time for a book that details an honest look into the life of Whitney."

The only things that are standing in the way of the book is a confidentiality agreement he signed when they divorce and plus the impact that the tell-all would have on his daughter Bobbi Kristina.

Friends of Whitney say, "This is a man who left his ex-wife's funeral because he didn't like his seats and went to a paying gig that night. He didn't get on stage that night because he needed to sing his greatest hits or because Whitney would have wanted him to entertain his fans, he did it to get a paycheck -- the same reason he now wants to write a tell-all book."

It was 36 years ago today (February 22nd, 1976) that Supremes' co-founder Florence Ballard died at the age of 32. The singer died of coronary thrombosis -- a blood clot in one of her coronary arteries. She has been cited by many friends and peers from the early Motown era as being the strongest singer of the three original Supremes, which included Diana Ross and Mary Wilson. Unfortunately for Ballard and Wilson, Motown chief Berry Gordy's plan to spotlight Ross on all of the group's singles pushed them into the roles of Ross' background singers.

Ballard was featured on several of the group's album cuts throughout the years, including "Buttered Popcorn" -- which was the group's third single, "Ain't That Good News," "Silent Night," "Heavenly Father," and her live solo spot, a cover of Barbra Streisand's "People."

Mary Wilson says she was amazed by Ballard's raw vocal talent and regrets that more people didn't recognize Ballard for her unique gift: "Florence actually was a great singer. In fact (laughs) every time I hear Etta James I think of Florence, because Florence had that same type of a voice as Etta James. And at a very young age. And had she lived, would've been really able to have really developed that style. I mean she would be like Aretha Franklin and Etta James today."

Former Temptations lead singer Dennis Edwards says that it seemed as though Ross' ambition ultimately forced Ballard into the shadows: "They say Florence actually was the best singer in the group. She didn't get the opportunity to be the best singer in the group, because Diana was a little bit more energetic. Y'know Diana was the type -- when she wanted something she got it, you know? (laughs)" )

When Ballard was forced out of the group in 1967 due to increasing personality clashes with the group and Motown, she was offered up a one-time severance payout of only $139,804.94. She unsuccessfully sued for back royalties in 1971.

She continued to record and perform occasionally and won a large legal settlement in 1975 after a "slip and fall" accident. Just prior to her death, she was reportedly making plans to begin recording again.

At her funeral, Ballard's Motown label mates, including Stevie Wonder, the Four Tops and Ross, came to pay their final respects. A tearful Ross was booed by fans outside the church, and was photographed sitting with Ballard's immediate family, including her two small children, at the service.

Ballard's work lives on in the numerous hits she recorded during her time with the Supremes. These included "You Can't Hurry Love," "Come See About Me," "I Hear A Symphony," "Baby Love," "My World Is Empty Without You," "Stop! In The Name Of Love," and many, many more.

Wilson says that that Ballard's emotional problems stemmed from being sexually attacked as a teenager: "Probably the main thing that destroyed her was being raped when she was 14 years old and we were still the Primettes, and that basically destroyed her. So people say that money and fame can make you happy and all that stuff, it really doesn't because it was always eating at Florence. And the minute that things happened to the Supremes that were bad, she was not able to do it because she was already weakened."

In 1999, author Randall Wilson published the first major book on Ballard's life, titled Florence Ballard: Forever Faithful!

In 2006 Ballard's sister Maxine "Precious" Jenkins began publishing an online book, titled A Life Supreme: The True Story Of Florence Ballard.

Ballard's time with the Supremes is said to be the inspiration behind the Broadway hit musical, and Oscar-winning movie, Dreamgirls.

Following her 2007 Golden Globe win for Best Supporting Role for Dreamgirls, Jennifer Hudson acknowledged the connection to the Supremes and why she dedicated her award to the Ballard: "'Effie' is loosely based on Florence Ballard and we did our research and we studied the Supremes. And in reading Florence Ballard's story it gave me the passion to want to deliver it. And I felt as if Effie was created as Florence's voice. So I felt it was my job to deliver on her end."

In 2010 it was reported that filming was expected to start shortly in Atlanta on the first biopic on Ballard's life and career. At the suggestion of Ballard's daughters, R&B star Faith Evans -- the widow of rapper Christopher "The Notorious B.I.G." Wallace -- will star as Ballard in Blondie -- The Florence Ballard Story. There's been no word as to when filming will start on movie, which is based on author Peter Benjaminson's book The Lost Supreme.

Former Guns N' Roses guitarist Slash confirmed what keyboardist Dizzy Reed recently told Billboard -- that the entire original band will be on hand for its induction into the Rock and Roll Hall of Fame in two months -- but denied rumors that they will be getting back together for a performance at the April 14th event in Cleveland.

Slash told Washington radio station DC101, "I know that there's a lot of rumor about it, as always when it comes to G N' R, out there on the Internet and stuff, but as it stands right this second, I have no idea what's going on."

Slash told us that no matter what else happens that night, being inducted is the best part about it: "I couldn't go as far as saying one way or another how I would fit into it, but it's definitely something that I feel honored to be called in for, you know."

The guitarist had issued an angry denial late last year when a Hall representative jumped the gun and said that the entire original band had RSVPed for the event. Slash said at the time that he had not yet indicated whether he was going or not.

Reed, who still plays in the current lineup of Guns, revealed to Billboard last week that all five original members will now be present when the group is inducted. He added, "I don't know exactly what's going to go down. It's one of those things I'm sure will all come together and be really cool."

Slash, singer Axl Rose, guitarist Izzy Stradlin, bassist Duff McKagan and drummer Steven Adler will all be inducted, along with later members Reed, drummer Matt Sorum and guitarist Gilby Clarke.

Slash, McKagan, Sorum and Adler have all express uncertainty about the possibility of a reunion at the ceremony.
