Hilary Duff Haylie Duff birthday car

Hilary Duff and her sister Haylie were spotted leaving Cecconi's in West Hollywood last night, and the girls (plus mom) were celebrating Hil's 23rd birthday. Hilary didn't seem to care about the paparazzi, but Haylie was just NOT in the mood for her close up. Wait a minute, who's the bigger star here?
