Don't mess with this Frozen fan!
In a two minute 28 seconds long clip uploaded to YouTube, the little girl is in the throes of belting out a melody when, off camera, her mum starts laughing.
The toddler was having none of it and so, in a reversal of the parent-child role - she snapped ( no doubt repeating a mantra she'd heard from her mother many times before):
"Do you want to be sent to your room and go and sleep by yourself and nobody will ever see you again? Is that what you want to do?
"Do you want to go on the naughty step and have a man take you away?"

The comedy moment was posted to YouTube where it has been viewed more than 800,000 times.
The little girl, from Belfast, looks pretty and proud as she stands in the living room in her blue silky Elsa dress.
But her mum soon loses the plot and dissolves into fits of giggles – much to the annoyance of her daughter.
The little girl wags her fingers and gives her chortling mother the dressing down of a lifetime – but nothing can stop the mum cracking up.
