Tina Turner vs. Elton John
During rehearsals for the 1999 “VH1 Divas Live,” music legends and close friends Tina Turner and Elton John found themselves at odds while preparing for a duet of Turner’s classic hit “Proud Mary.” Turner attempted to persuade John to play the piano a certain way during the performance, which offended John, leading to an onstage verbal battle between the two. John apparently stormed off stage after telling Turner that she doesn’t tell him how to play the piano. John apologized at a later, but Turner decided to cancel their upcoming world tour together and the two have allegedly been distant ever since.
