Keyshia Cole paid tribute to one of her idols, Mary J. Blige, while on R. Kelly’s “Love Letter” tour. The Oakland songstress once again covered the Queen of Hip-Hop Soul’s My Life classic “I’m Goin’ Down,” originally performed by Rose Royce in 1977, live at the NOKIA Theatre in Los Angeles last night. She had the audience singing along to her soulful rendition. Let us know what you think of Keysh’s cover.
