Grammys tributes
Houston's death has cast a huge shadow over the Grammy awards - the US music industry's night of nights.
Grammy executive producer Ken Erhlich said Jennifer Hudson and Chaka Khan will pay "respectful musical tribute" to Houston.
Her death was "too fresh in everyone's memory to do more at this time," Erhlich said according to the Los Angeles Times, "but we would be remiss if we didn't recognise Whitney's remarkable contribution to music fans in general, and in particular her close ties with the Grammy telecast and her Grammy wins and nominations over the years."
Houston won six Grammy Awards over the course of her career, and performed live at the 1986 and 1987 ceremonies.
As the pre-telecast awards ceremony began, co-host Dave Koz acknowledged the tragedy, noting the "great legacy of Miss Whitney Houston. She's in our hearts and our minds''.
