The night started to unravel when the R&B group (now three members strong after founder DeVante DeGrate exited) arrived at Enmore Theatre in Sydney without Dalvin. According to reports, the singer pulled out at the last minute.

Brothers Cedric and Joel Hailey, a.k.a. K-Ci and JoJo, were left to perform as a duo. But fans began booing and tossing bottles at the stage because they forgot some song lyrics and, at one point, even sat down.

The lowlight, however, took place during a sloppy rendition of "All My Life." That's when Jo-Jo simply passed out and fell to the stage. K-Ci looked at him briefly, then continued performing. A security guard walked toward Jo-Jo, but only to retrieve the microphone that had fallen out of his hand and rolled several inches away.

Eventually, Jo-Jo came to and was helped off stage by K-Ci and the security guard. K-Ci later explained to the audience that they were tired after their 24-hour flight and that JoJo had gotten dizzy."

UPDATE:
Appearing on Hot 97's Cipha Sounds & Rosenberg on Monday, K-Ci is now changing his tune. He claims his brother Jo-Jo suffers from epilepsy and has seizures which caused him to pass out Saturday night in Australia.
