Hipster hottie Grace Dunham is a fresh-faced, be-freckled and fantastically-endowed woman to watch out for. Little sis to quirky and quippy Lena Dunham, this lanky and lovely little lady has been more of a behind the scenes gal than her celebrity sibling, but we want to know what's she's hiding back there! We've already gotten to see big sis bare her bod more times than we can count, now we're holding out for you, Grace, so giddy up! Aside from clips in a couple film shorts, the only film presence that graceful Grace has given her fans is an autobiographical performance in Lena's breakout movie, Tiny Furniture (2010) that put these sexy sisters on the map. Grace did give us a sneak-peak at her gorgeous Girls when she spent a memorable scene busting out of a form-fitting sports bra that made us squirm in our lazy-boys. One thing we know for sure is that those cushions were anything but Tiny! This college cutie might not have any nudity to her name just yet, but we know this free-spirited family loves getting freaky, so we can be sure that there's a lot of feisty fun to be had in our future.
