Diva-licious: Tina Turner, Cher spice up stage with Oprah
Oprah's turning up the heat in Vegas when she takes her show on the road and takes stage with mega-hits Tina Turner and Cher.
Oprah will film a show next week with the duo scheduled to air May 8, according to The Insider.
The show will be taped at The Colosseum at Caesars Palace -- where Cher is slated to perform a slew of some 300 upcoming shows.
The last time Oprah shared a stage with Turner, she donned a Tina-like wig for the act.
