NEW YORK  - Whitney Houston was laid to rest on Sunday in a private burial before family and close friends near her birthplace in Newark, New Jersey, more than a week after her sudden death shocked the world. The pop star, whose powerful voice fueled her rise to fame in the mid-1980s with self-titled albums that made her a global pop star, died in a Beverly Hills hotel room last week. She was found underwater in a bathtub, but an exact cause of death has yet to be determined.
