It’s so nice to see a celebrity couple–even if they’re of the less “ohmygod, it’s THEM” variety–just looking happy and relaxed with each other. Not going overly PDA when they notice a camera pointed at them (I’m looking at you, Tomkat) or getting super pissed off–just going with the flow. That’s how Josh Jackson and Diane Kruger looked while taking a stroll on Saturday in London.

She’s there filming “National Treasure 2″ (c’mon–is there a need for this movie? The first one was fun, but a sequel?) and he’s keeping her company (I still hear he has signed on as the new “Fletch,” but no official announcement has been made yet). Hell, she even played photographer when a fan wanted a picture with Josh. And I have to admit…it’s cute. Look, I’m not made of stone, people. Underneath the hard cynical exterior is, well, a soft, nougat cynical center, but every now and then I can look passed that and say “awww, that’s sweet.” Of course, I fully admit I am biased when it comes to Mr. Jackson, as I have met him and found him to be not only absolutely adorable, but charming as Hell.

Then, on Sunday, the two were spotted at the Guards Polo Club for the “Rock the Polo: Cartier International Day” event. See what I mean? Very, very pretty–oh, and Diane looks fine, too.
