Lily-Rose Depp is one of the smartest celebrity teens in Hollywood [1], and given the fact that she just blazed her way through Cannes [2] in May, she's only getting bigger. When it really comes down to it, though, the daughter of Vanessa Paradis and Johnny Depp [3] also seems to enjoy being an average teenager. Case in point: Lily recently attended a high school prom in LA. Various Instagram snaps from the evening showed Lily looking gorgeous in a floor-length gown [4] and posing with a group of friends that included filmmaker Kevin Smith's daughter, Harley Quinn. He posted a stunning snap of the pair on Instagram and revealed they both had dates for the big night. Check out more snaps below!
