Whitney Houston Death

The L.A. County Coroner's findings on Whitney Houston's death has not settled the case -- by a long shot. Fingers are pointing in all directions, casting blame.

So we gotta ask ...

Ray J is pissed that people are accusing him of being Whitney's enabler and, even worse, fueling her with the fatal dose of cocaine.

Ray J's rep tells TMZ ... the singer had NO KNOWLEDGE that Whitney was using again.

The rep says Ray J is especially upset at claims made by Bobby Brown's sister, Leolah Brown, who went on TV Thursday night and suggested Ray J was to blame for Whitney's demise. Ray J says the claim is absolute B.S.

Sources connected to Whitney Houston who were with Whitney the day she died tell TMZ ... an individual removed all traces of cocaine from the room before authorities arrived.

The Coroner's Office says Whitney used cocaine "immediately prior to her collapse." Investigators who arrived on scene found no traces of cocaine or any other illegal substance.

One source who is extremely close to the situation tells us ... the individual who removed the cocaine was also the person who supplied it to Whitney.

As we previously reported, other items were removed from the room as well, including bed sheets.

An official for the L.A. County Coroner's Office just stated ... Whitney Houston used cocaine immediately prior to her death.

Coroner Chief Craig Harvey just held a news conference -- claiming the toxicology results suggested Whitney was a "chronic" cocaine user.

Harvey described the cocaine level in Whitney's system as "acute" -- indicating Whitney used the drug not long before she accidentally drowned in a bathtub at the Beverly Hilton hotel last month. "Accidental drowning" is listed as Whitney's official cause of death.

According to Harvey, the autopsy revealed a 60% narrowing of Whitney's arteries -- a direct result of the chronic cocaine use. Harvey claims the artery constriction led to a cardiac event before her death.

As for the other drugs in her system -- marijuana, Benadryl, Flexeril, and Xanax -- which Harvey claims were all at or below therapeutic levels ... and did not significantly contribute to her death.

Whitney Houston had cocaine in her system when she died -- this according to the L.A. County Coroner.

The L.A. County Coroner has just released the singer's official cause of death -- accidental drowning ... but the report also notes heart disease and cocaine use were contributing factors to Whitney's demise.

Officials say Houston also had traces of marijuana in her system ... as well as Xanax (anxiety medication), Flexeril (muscle relaxer) and Benadryl (allergy medication).

A source connected to the investigation tells us it is "very possible" Whitney had a heart attack that caused her to lose consciousness and drown. The heart attack may have been triggered by hardening of the arteries as a result of cocaine use.

As we previously reported, Whitney was found dead in a bathtub at the Beverly Hilton hotel last month and several pills were found on the scene -- including Xanax, Ibuprofen, and Midol.

Investigators found NO EVIDENCE of cocaine in the hotel room.

Law enforcement sources have told us from the beginning they did not suspect foul play -- and believe her death was not a homicide.

Her family however had doubts about Whitney's demise -- suggesting there may have been foul play.

3:01 PM PST -- The Houston family has released a statement which says, “We are saddened to learn of the toxicology results, although we are glad to now have closure.”

Whitney Houston's mother Cissy was shocked that her daughter was using cocaine at the time of her death but believes the relapse was triggered by anxiety over Whitney's comeback plans.

Sources very close to Cissy who have spoken with her in the last few minutes tell TMZ ... she believed her daughter was completely sober while shooting the movie "Sparkle."

But Cissy says as Whitney got closer and closer to the Grammys -- where Whitney would make her comeback move -- she fell prey to the drug.

Cissy is saying hearing that Whitney was using again is like reliving her death -- it's that painful.

Ray J is adamant ... he is NOT secretly harboring a stash of sexually explicit photos and video, depicting him and Whitney Houston in the throes of passion -- because no such stash exists.

There have been reports ... Ray is sitting on a hoard of sex tapes and XXX photos -- holding them over the Houston family as ransom -- because he knows they're worth a pretty penny.

But Ray J's rep tells TMZ, "The despicable tabloid report released today claiming the existence of a sex tape between Ray J and Whitney Houston is not true ... There is no sex tape."

Looks like no one is immune from thinking it is weird that Bobbi Kristina Brown is dating the guy she used to consider her "brother" -- because even their closest friends were shocked by the news ... TMZ has learned.

As TMZ first reported, Bobbi feels she's doing nothing wrong by dating Nick Gordon, the guy her mother Whitney Houston unofficially adopted 10 years ago.

According to our sources, Bobbi broke the news to her friends at a BBQ this week ... and no one believed it until the two kissed in front of everyone. We're told one friend felt the "relationship" was the result of each of them taking the death of Whitney too hard ... but they both brushed off that notion.

Our sources say the rest of the BBQ was quite awkward after that and everyone just tried to change the subject.

Whitney Houston's daughter Bobbi Kristina isn't fazed by her granny's accusations she's committing incest by hooking up with her "adopted" brother -- telling friends, she's gonna do what she wants ... no matter what.

Sources close to BK tell TMZ, the 19-year-old finally 'fessed up to her close buddies ... she and 22-year-old Nick Gordon are dating -- ten years after Whitney unofficially adopted the boy because he was having problems at home.

TMZ broke the story ... Bobbi's grandma Cissy Houston saw the video we posted -- showing Bobbi and Nick holding hands and kissing on a lunch run in Atlanta this week -- and told a close friend, "What [Bobbi and Nick] are doing is incestuous."

But Bobbi couldn't care less -- telling friends ... she doesn't give a damn about what Cissy thinks about her controversial relationship ... and because Nick's not her blood brother, she definitely doesn't consider it incest.

As one source put it -- Bobbi "can't please everyone, so she is going to please herself by doing what she wants to do for once."

As for the maybe engagement ring Bobbi was wearing -- we're told she's been mum on what it means ... but cryptically told friends, she and Nick ARE planning a trip to Vegas in the near future.

Cissy Houston -- Whitney Houston's mom -- has reacted fiercely to the video we posted Wednesday ... showing Bobbi Kristina and Whitney's "adopted" son Nick Gordon in a romantic grip, and then kissing (below).

Cissy told a close friend, "What they're doing is incestuous." Cissy feels her granddaughter has problems and Nick is taking advantage of her.

Although Whitney never formally adopted Nick, she considered him her son and Bobbi called him her brother. For his part, Nick called Bobbi his sister.

Whitney Houston's daughter engaged in some hardcore PDA -- including a kiss -- with her secret BF yesterday ... a guy who happens to be her pseudo-adopted brother ... and TMZ has the video.

19-year-old Bobbi Kristina was seen in a full-on lip-lock with 22-year-old Nick Gordon during a lunch run in Atlanta Tuesday ... confirming suspicions the two are romantically involved.

As we previously reported, Nick and Bobbi go way back ... when Whitney unofficially "adopted" Nick into the family roughly 10 years ago after learning Nick was having problems at home. He's been living with the Houstons ever since.

Again, Bobbi and Nick share no blood relation ... but we still gotta ask ...

Whitney Houston's sister-in-law Pat is throwing more fuel on the fire for those people who think Whitney may have been murdered ... saying she does not know how Whitney ended up in the bathtub of her hotel room on the night she died.

As TMZ first reported, the L.A. County Coroner's Office has received phone calls and emails from people claiming to be relatives of Houston ... who say they believe Whitney was murdered.

Bobbi Kristina says she can't bring herself to listen to her mother Whitney Houston's music just yet ... but she says she can "still hear" her mother's voice talking to her sometimes.

Bobbi, along with several Houston family members, sat down with Oprah Winfrey for an interview that aired tonight on OWN.

Whitney Houston's daughter Bobbi Kristina Brown can't stand her name ... because of its association with her father Bobby Brown -- and now, TMZ has learned, she wants to change it all together.

Bobbi Kristina is telling friends ... she's wanted to change her name for years -- ever since her parents split -- but Whitney wouldn't let her.

Now that Whitney's gone, we're told the 19-year-old feels untethered -- and wants to finally change her name completely ... making it simply "Kristina Houston."

We're told Bobbi has made the decision with a sober mind and is in a "better place" than she's been in a while.

It's unclear when she plans to make the change official.

Without mentioning her by name, Ray J told reporters yesterday he is "still hurting" from the death of Whitney Houston and that he's been having a "tough time" since she passed.

Ray J was at an event to support the Brotherhood Crusade and Mothers in Action Organizations ... and he knew the increased media presence was there because of his relationship with Houston.

So he decided to address the issue without being asked, telling reporters, "I really miss my friend, you know, I really do. I’m still hurting."

Ray J said he still keeps a picture of Whitney on his phone and looking at it helps him through the day.

Whitney Houston's brother Gary Houston isn't bothered one bit that Whitney snubbed him in her will -- telling TMZ, "I dont concern myself with any of that [will stuff] ... All I know is my sister's gone."

Gary just arrived in New York from Atlanta -- where a hearing was held yesterday naming his wife Pat the executor of Whitney's estate -- and we asked him about Whitney naming her daughter Bobbi Kristina as the sole beneficiary of her estate.

Gary left the airport with his wife Pat by his side -- who tells us, she's coping with Whitney's death "day by day."
