Diana Ross: 'My Heart is Hurting'

Michael Jackson and Diana Ross co-starred together in 1978's "The Wiz" and the Motown maven says she "can't stop crying" since she heard about Jackson's sudden death.

Ross says, "I am unable to imagine this. My heart is hurting. I am in prayer for his kids and the family."

Ross and Jackson were close since he appeared onto the music scene in the 1960s. The pop phenomenon's 1988 hit "Dirty Diana" was rumored to be written about Ross.
