Ozzy Osbourne will skip a scheduled appearance at Spike TV's Video Game Awards to make time for Queen Elizabeth II.
"The Prince of Darkness" was invited to perform at the annual Royal Variety Performance in Cardiff, Wales, on Nov. 21, Osbourne's spokesman, Lathum Nelson, said Tuesday.
Osbourne, 56, will join an international slate of entertainers that includes Andrea Bocelli and the Blue Man Group. His wife, Sharon, will also participate.
