The 28-year-old hitmaker was performing on a stage in Dublin, Ireland as a part of her "Anti World Tour," reported E! online.
Instagram videos of the concert shows RiRi singing the first few lyrics of her famous hit song with Eminem "Love the Way You Lie" with tears in her eyes.
When the crowd sang the song back to her, she got engulfed in emotion and stepped back with her hand in the air. Later she attempted to continue with the track, but kept getting choked up.
