Living legends Cher and Tina Turner will guest star in an upcoming episode of Oprah, both talking about their careers and performing in their senior years. It is their first joint interview ever.

Cher is performing at Caesar’s Palace, while Turner is embarking on another tour in October, which follows her praised appearance at the Grammys.

The two divas also perform a duet of ‘Proud Mary’ together. It’s been a long time since both sang together. Turner was previously a guest on the Sonny and Cher Comedy Hour in the early 70′s.
