It's set to go down at this year's Billboard Music Awards show on Sunday with Alicia Keys confirmed to duet with music legend Stevie Wonder.
The line-up already includes performances from Chris Brown, Justin Bieber and Usher, but the newly-announced pairing is arguably the true high point of the night.
Wonder/Keys (future group name, right there) have collaborated on stage before at the 2004 MTV Video Music Awards where they performed 'Empire State of Mind Pt. 2' and Stevie's 'Higher Ground' alongside Lenny Kravitz.
Alicia, who has won 10 Billboard awards herself, will also be presenting the Billboard Icon award to Wonder on the night.
