Demi Moore [1] turned Harper's Bazaar's 150 Most Fashionable Women event in LA into a family affair on Friday night. The 54-year-old actress arrived in style with her two daughters, 22-year-old Tallulah and 25-year-old Scout Willis, whom she shares with ex-husband Bruce Willis [2]. The trio looked all kinds of cool in matching floor-length gowns and served up some serious face while posing for pictures. Even though their older sister, 28-year-old Rumer, wasn't in attendance, she did share an Instagram snap of herself FaceTiming with Scout [3] earlier in the day, writing, "Morning FaceTime chat with my ride or die Icarus and of course my beauteous seestra @scoutlaruewillis." We just can't get enough of this family's close bond!
