'Price Tag' Jessie J has hit out at people who choose to wear real fur in a series of Twitter posts.

Many celebrities and popular figures take stands against the unethical treatment of animals and Jessie J has now joined the ranks, writing (November 16):

"Ugh seeing so many people wearing real fur.. #Nothanks #winterwardrobenono's"

When one of her fans suggested she takes part in PETA's anti-fur campaign, she replied by saying: "I should right."

The sensation also told her 6.2 million followers that the reason she hasn't been as active on the social networking site as usual is because she's committing most of her time and energy to her forthcoming new album:

"I know I'm distant. But I'm really in my album zone. Making it fantabalouso! Its a detailed process and I won't rush it :) #music #art"
