At this year's MOBO Awards Kelly Rowland performed her hit duet with David Guetta "When Love Takes Over." She was apparently livid after experiencing some sound-related technical difficulties in the beginning of the performance. After the performance she twitted:

"OK. So, I'm at the MoBo's and getting ready to have a GREAT show with David and the MoBo's F'd my sound up! PISSED! HONESTLY, that just makes me work harder! But, what I will say is the MoBo's owe me an apology! I was LIVID after the show!
