Hayden Christensen and Rachel Bilson are engaged, according to the New York Post' s gossip column, Page Six. Bilson formerly dated her The O.C. co-star and onscreen love interest Adam Brody for two years, but they split in 2006. She met Christensen, who rose to fame in the Stars Wars movies, when they co-starred in Jumper (2008). According to Page Six, a source spotted Bilson with her mother on a Virgin America flight from LA to NYC. "A man sitting in front of her on the plane saw a ring on her finger and asked if she was married," said the witness, who overheard Bilson reply, "I'm not married yet, just engaged. I know I look like I'm 15, but I'm actually 27." Christensen, also 27, is a Canadian actor who was born in Vancouver and raised in the Toronto area. The two recently spent some time in Uxbridge, just north of Toronto, where Christensen is building a farm home. A date has not yet been set for the wedding.
