Kelly Clarkson belted out a ballad from her new record in the New York City subway.
The 41-year-old's voice echoed through the platform, joined by a cadre of back up singers who harmonized with her on Mine, from her new album Chemistry, in a video shared on YouTube.
The collection of soon-to-be hits about love, loss and survival was released Friday.
Kelly, who has been spending time in the Big Apple to promote the record, looked business casual in a black and white print long sleeved dress with a handkerchief hem, black stockings and sneakers.
The performance seemed to have been part of a flash mob, similar to one the hitmaker put on at a coffee shop June 10 in Los Angeles.
