Demi Lovato has branded her critics "mean" after she was blasted for not attending the 2014 People's Choice Awards on Wednesday night (08Jan14).

The Heart Attack hitmaker came under fire on after failing to accept her awards for Favourite Female Artist and Favourite Music Fan Following in person.

The singer took to her account on the microblogging site on Thursday (09Jan14) to remind fans she is taking a month-long break from work, and she also hit back at her critics.

She wrote in a series of posts, "Damn... Just hopped online to check twitter and some 'fans' are being really mean... I'm not a (at) the Pca's (People's Choice Awards) because as I have stated before, I'm taking as much time off this month as possible... I haven't taken a substantial amount of time off in a long time and now I am.

"Thank you for those who voted and understand why I am away... There are 'fans' who say they support me, then they hate on me, my personal life and my loved ones... And then there are my Lovatics!!! They are the Best fans an artist could ever ask for... I Love You!!!"
