10 celebs who refuse to work with these stars again (With Pictures)

2. Jennifer Lopez, Mariah Carey

Mariah Carey has always made it clear that she doesn’t like Jennifer Lopez, and quite frankly, people have never understood why. It is unknown whether the two ever had a falling out between one another, but Mariah has publicly addressed the matter, saying “she doesn’t know” who Jennifer Lopez is. Then in a follow-up interview, Carey throw subliminal digs at J.Lo, saying that the songstress can’t sing. While Lopez is confused over the one-sided ‘90s feud, too, she wishes Mariah nothing but the best and just hopes the two never cross paths.
