Add Lady Gaga to the quickly-growing list of singers puking on stage. It happened at her show in Barcelona this past weekend. Here's the video:

I love Gaga. And I love how she toughs through it. That's gotta suck.

The best part to me though, is the backup dancer. You can tell there was a moment where he was like "Holy crap. This is my moment. I must DANCE!! DANCE like the superstar I am!! Mother Monster depends on me. DANCE!!!!!!"

PS - And by "quickly-growing list" I mean Bieber and Gaga. Guess it's really not "a thing" yet... but whatever.
