It was reported that Swift would only be a presenter at this year’s iHeartRadio Music Awards, but the pop star shocked us all by joining the “Material Girl” on stage.
The performance kicked off with only Madge visible to the audience, but the camera slowly panned to reveal Swift on the guitar sitting next to her.

The performance ended with Madonna giving Swift a kiss… on the cheek before walking off arm-in-arm.
Taylor Swift was already an early winner of the night and was at a loss for words when she won for "Best Lyrics" for her hit song, "Blank Space" and later winning "Song of the Year" for "Shake It Off" and "Artist of the Year."
The 2015 iHeartRadio Music Awards aired live March 29 at 8pm ET/PT on NBC, and simultaneously on iHeartMedia stations nationwide and across the iHeartRadio digital music platform.
