Ariana Grande kicked off her new "Sweetener" tour in the US on Monday with a tribute to her late ex Mac Miller.
Fans attending her first show realized that before her opening song, Grande played Mac Miller's music for the crowd in a subtle nod to the late rapper.
Grande and Miller dated for two years, but broke up last May.
Miller died from an overdose in September, just a month before Grande's split from fiance Pete Davidson.
