Britney Spears dons thong bodysuit on Instagram, calls out critics

Britney Spears isn't done calling out her critics.

Posting two nearly identical photos in which the "Toxic" singer is standing up in a red lace bodysuit, she wrote in a caption: "Second pic is the original and you heard me … should I say it again ?????? KISS MY MOTHER F---ING A--!!!!!"

In the photos, Spears' long, blond hair falls past her shoulders and she's wearing bold black eyeliner. She also bared her backside in the thong bodysuit.
