Beyonce made her displeasure known when things didn't entirely go to plan during a recent show in Rotterdam, Holland.

The singer was channelling alter-ego Sasha Fierce on stage when the lights failed to go up on cue, prompting the Bootylicious star to sing, "LIGHTS! Somebody's gonna get fired."

Last week, Beyonce laughed off claims she sent a look-a-like along to a personal tour of Vienna's Albertina museum because she was too busy shopping.

When asked about the doppelganger story, her rep said: "That's a real dumb one. (There's) only one Beyonce."
