Trouble in paradise??
We kid, we kid!
But it seems Justin's birthday weekend had to be just that because Jen was spotted at LAX catching a flight out of town.
We're guessing she's headed off to do more work, possibly some filming for Squirrels to the Nuts??
But if that's the case, what's Justin up to? Will he join her on set or during promotions?
Maybe he's just busy still recovering from his major 42nd birthday party and just couldn't get on a plane! LOLz!
