Actress Rachel Bilson and longtime boyfriend actor Hayden Christensen are engaged according to sources. The pair reportedly got engaged quietly in December over the holidays. But the news just broke when Bilson was spotted on a Virgin America flight from LA to JFK Monday night with her mom. "A man sitting in front of her on the plane saw a ring on her finger and asked if she was married," Bilson reply, "I'm not married yet, just engaged. I know I look like I'm 15, but I'm actually 27."
Reps for both Rachel and Hayden have yet to confirm the news. But a friend commented that "They're so excited," adding that no wedding date has been set, but "They're a great couple. Rachel seems thrilled beyond belief."
