Celine Dion, Jennifer Hudson and Usher are to lead the lineup of performers for a Whitney Houston tribute to tape in Los Angeles next month, CBS announced. Houston accidentally drowned in a hotel bathtub last February after using drugs shortly before she was to attend the Grammy Awards ceremony. She was 48. CBS said Thursday the tribute "We Will Always Love You: A Grammy Salute to Whitney Houston" will be taped Oct. 11 at the Nokia Theatre L.A. LIVE. "The one-hour special will celebrate Houston's life, artistry and most memorable performances through interviews with and performances by various artists paying homage to the six-time Grammy winner," a synopsis said. The program is scheduled to air Nov. 16.
