Ariana Grande’s latest concert took an emotional turn.

Ariana paid special tribute to her late ex, Mac Miller, during her concert in his hometown of Pittsburgh Wednesday night. According to concertgoers, she played the rapper’s music over the speakers at PPG Paints Arena before she took the stage. She also reportedly had an empty seat reserved for him.

“At the Ariana Grande concert in pburgh and Mac’s album is playing throughout the stadium before the show <33,” one fan tweeted.

Another wrote, “Ariana really had a Mac Miller playlist for the music before the show and she had an empty seat reserved for him. she’s so strong.”

During her opening performance of “Raindrops (An Angel Cried),” which is thought to be about the end of her relationship with Mac, she broke down and was unable to finish the song. She choked up again when she tried to sing the line “Wish I could say thank you to Malcolm/’cause he was an angel” in “thank u, next” – Mac’s birth name was Malcolm McCormick. With the help of the crowd, she made it through the song.

Miller died in September at the age of 26 from an accidental drug overdose. He had fentanyl and cocaine in his system at the time of his death. The two had dated from 2016 to the spring of 2018.
