Proudly rocking her denim short shorts, Rachel Bilson was seen taking an after lunch stroll with a gal pal in West Hollywood today (August 5).

During her calorie-burning jaunt, the former OC cutie looked a bit contemplative — until she saw the paparazzi, that is!

After greeting her adoring shutterbugs with a smile, Miss Bilson was merrily on her way as she tended to an afternoon of shopping.

Meanwhile, Rachel recently denied reports that she has split from fiancé Hayden Christensen after sparking rumours of a separation when she was spotted without her engagement ring at a party in Los Angeles. “The engagement is on,” said her rep. “She just doesn’t always wear the ring.”
