As the old saying goes, "The couple that flies together, stays together." (OK, we made that up.)
And while the pretty pair was all bundled up upon their arrival, the two soon found themselves having to slip off their respective cardigan and coat as they made their way through security.
You know, just the like the rest of us.
The last time we saw Christensen at LAX was back in January, when the actor was gracious enough to take time out to sign autographs and pose for selfies with a number of fans.
Meanwhile, Bilson recently talked to Cosmopolitan, telling the mag, "I definitely have family on the brain. Having kids is something I want to see in my future."
Well, she and Christensen would certainly make some beautiful babies!
