K-pop star HyunA fainted on stage during her performance at the outdoor Waterbomb Macau festival last night (Nov 9), sparking concern among fans and concert-goers.

In videos captured of the incident, the 33-year-old is seen dancing to her hit song Bubble Pop! (2011), doing body rolls before suddenly collapsing to the floor. Two background dancers rush to her aid, followed by a security officer who carries her safely off-stage.
