Oops, you're right, I meant to type 2/3 his height, or 1/3 shorter than him.  It's pretty hard to tell since she's perpetually sitting down and oozing to either side, but it's still probably an exaggeration. He's probably 6'2-6'4 and she's somewhere between 4'8 and 5'0 if you're really that curious. The part about having no definable neck is no exaggeration though. I have never seen anyone else that looks that bad, even in movies.
