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 annoying 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."
