Whitney Houston’s Tragic End Over Kim Kardashian Sex Tape

Kim Kardashian first found fame with a notorious sex tape — but the shocking video also sent Whitney Houston into a downward spiral leading to her fatal overdose on February 11, 2012!

The troubled pop diva had finally split from husband Bobby Brown (pictured) in 2007 — leaving a volatile drug-fueled marriage that had turned her into a national joke. She was soon in a serious relationship with rising rapper Ray J, who was then best known as the younger brother of pop star Brandy. But the new romance was soon broken up over Ray's porn video with Kim!

The troubled pop diva had finally split from husband Bobby Brown (pictured) in 2007 — leaving a volatile drug-fueled marriage that had turned her into a national joke. She was soon in a serious relationship with rising rapper Ray J, who was then best known as the younger brother of pop star Brandy. But the new romance was soon broken up over Ray's porn video with Kim!

"Ray really helped Whitney in her fight against crack addiction," said an insider. "He cut out club-hopping to stay home with her." But that was before Whitney found out that her new love would be seen by millions having kinky sex with Paris Hilton's former personal assistant!

"Whitney was heartbroken," confided the close pal. "She thought Ray J was just the guy to bring her back from the edge." And Ray J made things even worse by trying to cover up his role in the video. "Ray denied it at first," said the pal. "She dumped Ray, saying she'd make it on her own."

But while Whitney later reconciled with Ray, his own newfound fame had reportedly lured him back into drugs. As revealed by The National ENQUIRER, the allegedly drug-free Kim can even be seen in sex-tape outtakes as she joins Ray in guzzling down booze and smoking dope!

Insiders claimed that Ray's new fame soon had him back on drugs, as well — with Bobby Brown’s sister Leolah saying that Whitney's lover was a "runner boy" who kept his love supplied with cocaine. Ray denied the accusation, even as Whitney's manager Patricia Houston blamed her client's addictions on "looking for love in all the wrong places."

In a final tragic twist, Whitney lost her life just weeks after The ENQUIRER revealed that she was almost ready to finally break up with Ray. Sources reported that Whitney had fallen hard for "Criminal Minds" star Shemar Moore — and they had even exchanged diamonds at Christmastime. The doomed diva was still seeing Ray, said insiders, who added: "But he likes to party, and she's trying to stay away from that lifestyle."
