Little Couple -- Still Trying for Little One

They're both under 4ft tall, but Bill Klein and Jen Arnold, aka TLC's "The Little Couple," are ready to bring someone smaller than them into the world -- a baby.

Yesterday, as the couple left Jimmy Au's -- a store for men 5'8" and under -- Bill revealed they're "still working on" having a kid, but due to health concerns they "just don't know how yet."

May we suggest a nice hotel, some champagne ... and let Marvin Gaye take it from there.
