Whitney Houston Dead: Artists React on Twitter

Whitney Houston died at age 48 on Feb. 11, shocking the world and those closest to her. Though she was known in her later years more for her troubles than for her hits, her voice will live on forever in hits such as 'I Will Always Love You,' 'I Wanna Dance With Somebody' and 'Waiting to Exhale.' Houston was mourned by artists across genres on Twitter the night before the Grammys -- an award ceremony that, in her prime, she would easily have swept.
