Grammys plan tribute to Mandela The producers of Friday's "Grammy Nominations Concert Live" say the show will feature a special tribute to Nelson Mandela, who died Thursday at the age of 95. Actor and rapper LL Cool J, who is hosting the show on CBS Friday night, shared some personal reflections on Mandela as well. In the video above, he praised Mandela for embodying "moderation, wisdom, truth, justice, courage ... principles that are eternal. He represented those principles. He joined an outpouring of public tributes honoring the former South African president, who led the fight against racial apartheid and inspired millions of people around the world. A rehearsal was already scheduled Friday for the Grammy nominations special, as producers adjusted plans to incorporate a Mandela tribute into the show. LL Cool J, a two-time Grammy winner, returns to host the concert for the sixth year in a row. The line-up for the one-hour special also includes Robin Thicke, Lorde, Keith Urban, Macklemore & Ryan Lewis, Katy Perry performing from Canada, and seven-time Grammy winner Taylor Swift appearing from Australia. The Grammy Nominations Concert Live airs on CBS at 10 p.m. ET Friday night.
