Delta Goodrem wowed American audiences yesterday with a stunning duet with Michael Bolton on Dancing With The Stars USA. The singers debuted Goodrem's "I'm Not Ready To Say Goodbye" which is featured on Bolton's upcoming album "Gems - The Duet Collection" (released in Australian 24th June, 2011). Delta also saved the day with a last minute solo performance of Carole King's "Natural Woman", replacing Adele who pulled out on the night due to voice issues.
