Grammys 2016: Taylor Swift slammed for off-key 'Out of the Woods' performance

Taylor Swift had the epic task of opening the 2016 Grammy Awards, but according to many, her performance fell flat. 

After belting out her latest single, 'Out Of The Woods', the 26-year-old was slammed on Twitter for her apparently off-key rendition. Have a listen for yourself, above. 

Perhaps she was overwhelmed after winning Best Pop Vocal Album before the ceremony began?

Whatever the reason, criticism was thick and fast for the hitmaker, with viewers critiquing her pitch, outfit and even haircut. Ouch. 

Shake it off, Tay, shake it off.
