Rachel Bilson Flashes Her Engagement Ring Bling

Newly engaged actress Rachel Bilson dons a floral Brian Reyes top and a tassled Zac Posen bag as she visits a friend at Main Street’s Piero Hair Salon on Wednesday (February 25) in Santa Monica, Calif.

The 27-year-old O.C. starlet flashed her engagement ring, which actor Hayden Christensen gave to her over the holidays.

When recently asked what her favorite and and least favorite thing about Fashion Week was, Rachel said, “You go blind with all the flashes, but it’s the price you have to pay to see beautiful clothes. I just love seeing everything firsthand, there’s nothing better.”
