Greatest of All Time pop queen Madonna and Greatest of 2015 pop queen Taylor Swift have already shared the stage together once before (they performed "Ghosttown" together at the iHeartRadio Music Awards), but their collaborative story isn't over yet.

In Andy Cohen's Madonna interview for Entertainment Weekly, Madge shared that she nearly took the stage with Swift during the latter's New Jersey tour stop, but a video shoot got in the way.

"I didn't get the chance to go see her show. I was kinda bummed," Madonna told Cohen when he asked her about her "Welcome to New York" Instagram to Taylor. "We were actually gonna do something together on stage, but I didn't go to the show because I was rehearsing and I had to shoot a video the next day. Going to shows requires free time."

When the Bravo host pushed for more details, Madonna stopped him cold. "I'm not gonna tell you, because we might still do it. You’re very nosy. You just want to know everything.”

Fingers crossed this happens, and fingers crossed Swift and Madge hit Watch What Happens Live together in the future.
