Puff Johnson, best known for R&B hits "All Over Your Face," "Over and Over" (from the film "The First Wives' Club") and "Forever More" succumbed to cervical cancer this week at the age of 40. She had also appeared with Tupac Shakur on his memorable hit "Me Against the World," and opened for Michael Jackson on his 1997 tour. Although she never broke through to a large mainstream audience, she was an outstanding vocalist and left behind the superb 1996 album "Miracle." R.I.P. Puff Johnson.
