Bella Thorne Caught in a Little White Furry Lie

EXCLUSIVE

0302-bella-thorne-with-cap-instagram-01Bella Thorne tried to silence Internet trolls but instead got caught in a tangled "faux fur" web -- 'cause it turns out the jacket is genuine rabbit and arctic fox fur. 

Bella posted the pic of herself in the fur coat Tuesday on Instagram and even tried to silence the imminent anti-fur backlash with a caption that read, "Dear internet trolls, it's faux fur."

Problem is ... people were quick to notice the fur looked identical to the Tierra Striped Fur Jacket by Alice & Olivia which retails for $1,700.

The item's description -- on the Bloomingdale's and Harrods websites -- specifically says it's made of GENUINE rabbit and fox fur from China, where fur farms are abundant.

A rep tells us Bella was given the jacket during a photo shoot, and was "told it was faux fur." The rep says now that Bella is aware ... she'll never wear it again.
