Sharon Osbourne admitted to sabotaging Iron Maiden’s performance at Ozzfest in San Bernardino a few weeks ago.

She has admitted to being behind their power being turned on and off throughout their performance and to eggs being hurled at the band by technical staff.

She said: “I did cut Iron Maiden’s sound. Every action has a reaction. Was [Bruce]Dickinson so naive to think that I was going to let him get away with talking about my family night after night?

“I don’t think he realises who he’s dealing with. I will not endure behaviour like this from anyone.”
