This is too classy for the world. MadonnaAnd Beyoncé will forever be those girls.

Just days after the duo released the “Queens Remix” of Beyoncé’s latest hit “Break My Soul”—and broke the internet in the process—Madonna shared the sweet thank you card she received from the “Lemonade” singer.

“Thank You, Queen. Thank you so much. Bey said, “You Have Opened so Many Doors for So Many Women.” She also included a beautiful white floral arrangement. In her message, Beyoncé also bestowed a new title upon Madonna, calling her a “masterpiece genius,” a Renaissance lyric from her new song “Alien Superstar.”

“You Are Masterpiece Genius. I am a masterpiece genius. Thank you for allowing me to sing in your song and thank you for naming the remix !!!!”. After signing the message, she added, “Love Always And Forever B.”

In response, Madonna gushed just as much about her latest collaborator. She replied, “Thanks!! From one 👑 to another 👑 I love the Re-Mix !.”
