The late Whitney Houston's death certificate (acquired by TMZ) confirms that the "I Will Always Love You" singer will be laid to rest at Fairview Cemetery in Westfield, NJ.

And family sources tell the site that the star had asked to be buried next to her father, John Russell Houston, who died in 2003.

A private, invitation-only ceremony will be held for the singer (who died Feb. 11 in Beverly Hills) at the New Hope Baptist Church in nearby Newark, NJ.

Meanwhile, as the investigation into Houston's shocking death continues, authorities are expected to question the doctors who prescribed Houston the prescription medications that may have helped lead to her death.

The results of a toxicology report are expected in several weeks.
