A headstone has been installed at pop star Whitney Houston\'s grave at Fairview Cemetery in Westfield, N.J., TMZ reported. The pink, heart-shaped marker reads: \"Whitney E. Houston. Aug. 9, 1963 -- Feb. 11 2012.\" Under that, the headstone says, \"THE VOICE\" and \"I Will Always Love You.\" TMZ did not say what took so long to put the marker on the grave. The Grammy Award-winning artist accidentally drowned in a Beverly Hilton bathtub after using drugs hours earlier, authorities said. She was 48. The singer is buried next to her father, John Russell Houston Jr., TMZ said.
