Taylor Swift and Madonna Own the iHeartRadio Awards

In a night that belonged to Taylor Swift, she hit her highest note at Sunday's iHeartRadio Awards alongside new BFF Madonna. Swift made a surprise appearance to provide guitar accompaniment for Madonna's performance of 'Ghosttown,' the new single from Rebel Heart and the awards show's best performance.

The alluring, post-apocalyptic song could well shape up to be a hit for Madonna, and she and Swift shared the stage with the ease of kindred spirits. Later in the night, Madonna presented Swift with the song of the year award for 'Shake It Off,' and Swift thanked 'Madonna for being Madonna.'
