Singer Taylor Swift got raunchy as she stripped off to show a tiny frock during her performance at the 2014 American Music Awards (AMAs) here.

The 24-year-old, who usually maintains a demure demeanour during her live performances, ramped things up at the Nokia Theater Sunday, reports mirror.co.uk.

While performing her new hit `Blank Space` for the very first time, Swift even gave the crowd a glimpse of her thigh when she pulled her frock up.

The `Never ever getting back together` singer began her performance with her latest hit while sitting on a long dining room table with a man.

The stage soon went on fire with a feisty Swift clutching a rose with fire coming out of her top.

Donning a rose gold frock, towards the end of the performance Swift turned things up by ripping it off to show a mini dress.
