LOL! We just watched a video on TMZ of a woman at the airport who was psyched to see Ashford and Simpson but was disappointed when she found out it was just Ashlee Simpson. And then she asked to take a picture with her! Too funny…

But the real news is that while fiancé Pete Wentz was talking to the camera, he let it slip that he and Ashlee are filming a reality show! "We're 15 minutes into this reality show we're doing right now, the car's still not here," he laments to the cameraman. "At this point we've realized we're gonna make a whole episode out of this." When asked the name of the show, Pete said, "How To Not Get Picked Up At LAX." (We know you like long, obscure titles for your songs, but maybe that's not the way to go with this one, Pete.) Anyway, you heard it here!

(P.S. -- Ashlee previously denied reports that she and Pete were doing Newlyweds 2, but if the show's about prepping for the wedding and they're filming now, then they're technically not newlyweds!)
