Well, Michelle Rodriguez didn't keep her promise, but we're cool with that.
The actress, who recently flashed some serious armpit hair in a holiday selfie on Instagram, captioned the photo with, "Merry Winter Solstice !!! It's a great time to remember that life can be as simple as letting go and remembering were all rentals in this world, love that anoying family member, kiss that bratty cousin, & hug the love your life real tight."
And she added, "I promise to shave my arm pits at some point before the New Year mad love and peace to all."
Rodriguez's vacation photos prove that she opted to leave the razor in the drawer, and continued to rock a bountiful underarm while enjoying her getaway.
