Getting an early start to the day, Rachel Bilson spotted leaving her Big Apple hotel to attend a New York Fashion Week on Tuesday (September 15).

Looking sexy in a cheerful, multicolored mini dress, the former “OC” star strutted past awaiting paparazzi before hopping into the backseat of her awaiting chauffeured ride.

Having been living it up in NYC for the past few days now, Miss Bilson spent the weekend alongside her “Jumper” co-star fiance, Hayden Christensen.

The lovely pair were among the many celebs dropping by the USTA Billie Jean King National Tennis Center to check out the US Open action.
