Rodriguez has been showing off her armpit hair quite a bit lately on Instagram, and last week, she promised to shave before the new year ... clearly, that hasn't happened.
The actress grew out her hair for her role in her upcoming film, Tomboy, a Revenger's Tale, a gender-swapping action movie. Rodriguez plays a male assassin who is turned into a woman by a rogue surgeon, after he's double-crossed by gangsters. The intense film is expected to hit theaters in 2017.
"Throwback Thursday looking back at hairy armpits and hairy face it will take some time but I'm so ready to go back to being a girl, had a great shoot this was a memorable film experience that's for sure... Tomboy will be a trip to see," she Instagrammed last month.
ET caught up with Rodriguez last August -- when she was trying out Call of Duty: Black Ops III in Santa Monica, California -- where she talked about wanting more female costars.
"The grand majority of the time in films, we're always fighting each other," she explained. "I feel like it's time to evolve girls. Let's stop hitting each other and let's stop fighting each other, and let's start getting together and ganging up on people."
