Ashanti brought her concert to a stop to go on a rant because her crew screwed up.

Last Thursday, she kicked off the R&B Jam Series at the Alex Madonna Expo Center in San Luis Obispo. 

She was in the middle of performing "Baby" when, out of nowhere, she stopped the show and ordered the video board turned off. 

She followed up with, “What the f—k they doing back there?” Ashanti's rep said there was a technical issue with the screen that was causing interference to her in-ears and choreography. 

Sounds like it wasn't the crew's fault but rather an equipment malfunction.
