Miley Cyrus is set to perform with Madonna.

The "Wrecking Ball" hitmaker has roped in the pop veteran to duet with her on her upcoming MTV Unplugged special. The unlikely pair were rehearsing on the Hollywood soundstage yesterday, with the collaboration due to air on Wednesday night.

"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 #1 critically acclaimed album, Bangerz. 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," MTV commented.

Miley, 21, has compared herself to Madonna in the past and believes they share the same love of controversy and risk-taking. "Last night, I was talking about some Madonna performances, and I said, 'At some point, everything becomes irrelevant.' Like, no one even thinks about when she did 'Like a Virgin' at the VMAs. That just becomes a standard, where it's just like, 'Oh, that's her thing.' So, I feel like now that I did the VMAs, that just kind of became a standard for me, and then any time I do anything else, they're like, 'Miley kept it tame tonight,'" she recently reflected.
