Singer August Alsina collapsed during a sold-out concert in New York City on Monday (15Sept14).

The No Love singer was performing at The Irving Plaza venue in Manhattan when he stumbled off the stage and fell into the audience. Security guards rushed to pick the star up and carry him backstage.

Witnesses tells Tmz that Alsina was carried out of the venue on a stretcher but was well enough to wave goodbye to his worried fans. Videos of the dramatic fall have since appeared on Instagram and Youtube.

Monday's gig was part of his Testimony Live tour. It is not known if the remaining tour dates will go ahead.
