As if they don't stir up enough controversy individually!

Miley Cyrus' MTV Unplugged special is set to air Wednesday, and the chart topper has included a surprise guest to perform with her - Madonna!

The "Wrecking Ball" singer and the music icon were reportedly at a Hollywood sound stage yesterday rehearsing, but it's unclear which songs they've chosen for their collaboration, E! Online reports.

"The performance will showcase a more intimate side of Cyrus and feature surprise guests for an unexpected re-invention of the songs that have defined her career, including several from her No. 1 critically acclaimed album, Bangerz," MTV said in a press release. "Miley and her fans have always had an intimate and direct connection through her music, personality and no-holds-barred attitude and the Unplugged stage will serve as the perfect platform for her to show viewers what inspires and ignites her music and her passions."

It has to be a dream come true for Miss Miley to be able to share the stage with Queen Madge!
