Tina TurnerSuperstar Tina Turner is coming out of retirement to make her first public live performance in eight years at The Grammy Awards. The 68-year-old singer will duet with Beyonce Knowles at the music Oscars next month. Turner announced her retirement in 2000, but took the stage for a private charity gig at London’s National History Museum last May. Now she’ll make a comeback by performing a song with Knowles at the Los Angeles awards ceremony. Knowles is a long term fan of Turner’s and performed her song Proud Mary at a Kennedy Center tribute to the veteran musician in 2005.
