Selena Gomez was pretty ticked at this year's KIIS FM Jingle Ball -- and to prove it, she finished her song, yelled "What the f---" into the microphone and reportedly stormed offstage, angry about an alleged sound issue. Check out the video -- she sounds pissed.
Lock it up, Selena. The audience was likely composed of adults as well as children, but guess what -- it was probably mostly children. Even if you thought your mic was off, it's not a big deal when people make mistakes anyway, right? Come on now.
