Two longtime AIDS activists are seeking to make beautiful music together on Oscar night: Mary J. Blige will join Elton John on stage for a duet at John's AIDS Foundation Academy Awards viewing party Sunday.

"Elton John is one of the most inspirational musicians and philanthropists in this industry for me," Blige said in a statement Tuesday. "I respect him with all my heart, and it is truly a pleasure to be performing with him on such an important night as we look to raise awareness and vital funds for the fight against HIV/AIDS."

John's annual Oscar party has raised more than $15 million over the past 15 years.
