Sexy Texan Jessica Simpson has had quite a week, from nearly popping her top at the Grand Ole Opry to flashing naked butt. Last night, she continued her week of wonders by making an appearance on Letterman, wearing a low-cut get up and helpfully shaking her famously oversized torso tonnage.


The singing sensation also claimed that she never knowingly jinxed boyfriend Tony Romo's football games, but one look at Jess's jiggling jugs and we were fumbling all over the place!

Watching Jessica move her lovely shoulders back and forth, back and forth, hypnotically, makes one wonder if this Southern gal secretly has some Mexican blood, because her maraca-shaking skills are unparalleled.

Now we know why Romo is so good with ball handling.

Fast forward and watch the Simpson shake around 5:20 in this vid (via Accidental Sexiness):
