Madonna And Taylor Swift Are Besties At The 2015 iHeartRadio Music Awards: 12 Pics

Madonna & Taylor Swift Do "Ghosttown"
Watch their joint performance at the 2015 iHeartRadio Music Awards.

Ladies and gentlemen, meet the newest¬†pop BFF power couple…Taylor Swift and Madonna!

The massively successful pop titans caused the biggest shock of the night by teaming up on stage for a somber, yet powerful performance of Madge’s new Rebel Heart single, “Ghosttown.” Later on, M returned the favor by awarding Taylor with the Artist Of The Year award. And by the looks of it, they’re pretty¬†enamored with each other!

The two record-breaking superstars also took turns paying homage to each other off-stage too, with Madonna Instagramming her #RebelHeart away (“My new favorite guitar player! Thank you Taylor! Just you and I in a #ghostown”) while Taylor went shaking and crying over professional pics of their collaboration on Twitter. #MyFangirlLife!

Could this new friendship lead to a musical collaboration down the line?
