Lionel Richie Tribute Adds Rihanna, Dave Grohl, Chris Stapleton, Florence Welch

Lionel Richie will be honored at a pre-Grammys event next month, and the list of performers has expanded to include Dave Grohl, Chris Stapleton, Florence Welch and Rihanna, who released her long-awaited eight album ANTI last night (!!!). Jimmy Kimmel will host the event and Stevie Wonder, Pharrell, John Legend, Luke Bryant, Usher, Lady Antebellum, Lenny Kravitz, and Demi Lovato will also perform. The Grammys air 2/15; read about why we don't think the award show will be all that bad this year.
