Super undercover couple Hayden Christensen and Rachel Bilson might be planning a super undercover wedding to one another. The two have done a pretty good job of flying under the radar but Page Six reports that Bilson spilled the beans on a flight from Los Angeles to JFK with her mother.

A spy revealed, “A man sitting in front of her on the plane saw a ring on her finger and asked if she was married.” In response Bilson said, “I’m not married yet, just engaged. I know I look like I’m 15, but I’m actually 27.”

And well, there’s not much more to say about it. Except that I’m sure they’ll elope and then make some tiny, quiet, poorly-dressed babies.
