Jess  and John stopped off in Adelaide on their airport tour of Australia . While I (clearly) love this couple, it's sometimes hard to find pictures of the two of them where he doesn't look kinda annoyed .* This time, though, he seems to just be slightly concerned that she is wandering away by mistake. I can only imagine how much of a lost puppy she can be at times, so it's probably best to keep an eye on her in public. See, he's just being sweet.
* I do contend, though, that he's fed up at the photographers in his face not Jessica herself (mustkeepbelievingthis).
