The Hilton Sisters
Ah, the early aughts. We definitely miss the heyday of wild celebutantes Paris and Nicky, since they've both slowed down (a bit) since then. We mean, sure, newly-engaged Paris is always down for a good party, but as of late you could find her working more on her domestic skills, while Nicky has of course settled down with a Rothschild, has two children, and is turning into quite the society queen.
