I haven’t seen Rachel Bilson pictured with Hayden Christensen in so long, I just assumed they had fizzled out. Apparently not, Page Six says Rach was rockin’ an big diamond and telling folks on a flight to New York that she is engaged.

A Page Six spy spotted Bilson on a Virgin America flight from LA to JFK Monday night with her mom and tells us the actress is engaged to longtime beau Hayden Christensen. “A man sitting in front of her on the plane saw a ring on her finger and asked if she was married,” said our snitch, who overheard Bilson reply, “I’m not married yet, just engaged. I know I look like I’m 15, but I’m actually 27.” Her rep didn’t return calls.

Hayden Chistensen’s new sci-fi thriller “Jumper” leaped to the number one spot at the box office over the weekend. Another case of critics panning something that real people love. Don’t you just love it when the critics get proved wrong? Here are some hot pictures of Hayden in the March issue of Details magazine to wet your whistle and get you to the theaters this weekend.

And here is the plot of the movie to further entice. A genetic anomaly allows a young man to teleport himself anywhere. He discovers this gift has existed for centuries and finds himself in a war that has been raging for thousands of years between “Jumpers” and those who have sworn to kill them.
