Mary J. Blige will join Elton John for a duet during Elton’s AIDS Foundation Academy Awards viewing party on Sunday.

“Elton John is one of the most inspirational musicians and philanthropists in this industry for me,” Mary says in statement. “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.”
