The 33-year-old singer was mid-song when the zipper on her black bodysuit broke, revealing her entire back.
Though several of her backup dancers tried to zip her outfit again, their attempts were unsuccessful.
She finished the song and then ran off stage to get the mishap fixed. (RELATED: Chrissy Teigen Suffers Wardrobe Malfunction When Slit Splits Five Inches High)
