Could Whitney Houston have died from natural causes? That's the theory being floated by the National Enquirer, which quotes a source who says she'd suffered from heart problems for years.

The insider tells the Enquirer that Whitney, who was born a premature baby, had never been totally healthy. The snitch says, "She didn’t talk about it a lot, but she knew that she had heart problems and her life was probably going to be cut short. Needless to say, she abused drugs. But whether or not she used drugs, she believed she’d never see her 50th birthday. Whitney knew she could drop dead at any time."

If Paris Jackson is going to live with her biological mother, Debbie Rowe, it's going to take a fight. The Jackson clan is adamantly opposed to that arrangement.

After Paris's apparent suicide attempt last week, Debbie has been in the press suggesting that the pressures of living in a celebrity family have gotten to her. Debbie has also said that she'd be happy to become Paris's legal guardian. As you may recall, the two have been spending time together the past few months.

But a source tells TMZ that the family believes Debbie has other motives, saying, "If her intentions were pure, she'd be speaking to the family." Oddly, though they think Debbie is trying to get herself into the spotlight, they don't believe she's after any of the Jackson family fortune.

Nonetheless, the source says the family plans to fight "tooth and nail" if Debbie throws her hat into the ring.
