Imitation is the sincerest form of flattery after all.
In a sit-down interview with Variety released Wednesday, The Weeknd accused Usher of wrongfully using his 2011 mixtape House of Balloons as inspiration for the 2012 track "Climax."
"I heard ‘Climax,' that Usher song, and was like, ‘Holy f--k, that's a Weeknd song,'" he told the publication. "It was very flattering, and I knew I was doing something right, but I also got angry. But the older I got, I realized it's a good thing."
Usher clearly caught wind of The Weeknd's remarks, taking to Instagram to sing an a cappella version of "Climax." Enter the #ClimaxChallenge, which was started by singer-producer Eric Bellinger to encourage The Weeknd to attempt to hit Usher's falsetto notes.
