'Stop it': The moment smiling Beyonce scolds assistant for fussing over her fierce plunging dress on red carpet

She's long been known as Queen B. And Beyonce  lived up to her nickname as she put her assistant in her place on Tuesday evening.

As the singer stood regally on the red carpet, cameras flashed as a hapless helper fussed over her low-cut dress.

Without dropping her megawatt smile for even an instant Beyonce coolly commanded she stop, and get out of her shot.

The power of Beyonce was clear, as the woman instantly fled to stand at a more appropriate distance.

She could then be seen watching as an unruffled Beyonce showed just what a professional she is, posing for the photographers as they shouted 'Queen'.

It was clear just why the assistant had panicked - Beyonce's dress left little room for error.

Cut incredibly low, it just skimmed her curves, daringly risking a wardrobe malfunction.
