Britney Spears did not leave much to the imagination in her latest Instagram post — sporting a teeny tiny red thong … and maybe even commenting on all her biopic casting rumors.

Brit changed it up Friday night when, instead of her usual dancing video, she posted a series of sexy shots in the thong and black lacy lingerie, with the caption … “Definitely a character because that’s not me !!! But wait shit it does kinda look like me 🤔🤔🙄🙄 !!! Just kidding !!!”

It’s not entirely clear what she meant … but perhaps she was commenting on the casting rumors of her upcoming biopic directed by “Wicked’s” Jon M. Chu.

If the gossip is to be believed … Sabrina Carpenter and Millie Bobby Brown are among the actresses being considered for the role — that Brit herself has the final say over. Of course, no one really knows where the process is at this point.

As for the new sexy snaps … it’s clear Britney has a new favorite spot in her house to make social posts … ’cause she keeps heating things up in front of that huge fireplace!
