The 14th Annual Wango Tango event in Los Angeles was held on Saturday May 14th at the Staples Center. Britney Spears was on hand helping Ryan Seacrest with the emcee duties.

Among the performers for the day-long concert were; Jennifer Lopez, Ke$ha, Selena Gomez, Cobra Starship, T-Pain, Lupe Fiasco, Cody Simpson, Far East Movement and ‘Glee’ star Matthew Morrison.

During her set, singer/dancer/actress/American Idol judge Jennifer Lopez proved herself the consummate professional.

A glitch in the Staples Center’s sound system caused all sound to go off in the stadium. But Lopez didn’t miss a beat and continued dancing and singer as though there was nothing wrong. Of course it wasn’t unnoticed by the fans…

One fan recorded the mess up and posted it to YouTube. Sound goes out around the 0:38 mark.

Yikes! Poor JLo!
