Ariana Grande cries on stage while honoring late ex-boyfriend Mac Miller

Ariana Grande enlisted the help of her fans as she sang an emotional tribute to her late ex-boyfriend Mac Miller on Wednesday night.

The 25-year-old singer choked back tears as she sang Thank U, Next to a packed stadium in Miller’s hometown of Pittsburgh, Pennsylvania on her Sweetener tour.

Grande stumbled around the lyrics ‘Wish I could say thank you to Malcolm,’ but the audience made sure to back up their favorite performer and helped her recover with a wild applause for the rapper.

Ariana stood in the middle of the stage with back-up vocalists on each side during the performance.

Pink lights highlighted the stage and fans could be heard singing the lyrics along with Grande.

In addition to her tributes on stage, she made sure to keep Miller’s music in fans ears as she played a few of his songs over the speakers at PPG Paints Arena.

Ariana went one step further with her remembrance and made sure to leave an empty seat reserved for Mac at her concert.

Mac (born Malcom McCormick) died from an accidental overdose at his home in Studio City, California on Sept. 7. He was 26.
