Which songs will Lady GaGa and Elton John duet at the 2010 Grammys?

Lady Gaga Concert Radio City Music Hall New York City

E! Online is confirming a duet between pop divas Elton John and Lady GaGa this Sunday at the 2010 GRAMMY Awards. They’ve got more details, including that it will be a melody of songs, presumably meshing two or more from each singer’s catalog. The costumes and set will be factory-themed, and one or both of them will bang it out on the piano. The thrills!

These two are pop theatrics magic, and when they get together onstage it may be too much for mere mortals to witness. The glitter alone could kill thousands.

Some possible mash-ups they may perform:

“Empty Gagarden”
“Tiny Bad Romancer”
“I Guess That’s Why They Call it the Paparazzi”
“Hermaphrodile Rock”
“Shiny Dancer”
“Saturday Night’s Alright for a Bad Romance”
“The B*tch Is Back”

This will probably even top Elton’s 2001 duet with Eminem, which was really, really amazing. In case you missed that:

The Grammy Awards will air live Sunday, January 31, 2010 @ 8 pm EST on CBS.
