JESSICA SIMPSON revealed on KATIE COURIC'S new show yesterday that she's lost more than 40 pounds . . . although she wouldn't give an exact number.

--She said, quote, "It's really not about the numbers.  I've lost enough weight where I can pat myself on the back."--She also revealed her new Weight Watchers ad, which does NOT include a full body shot.  That was her choice.--She said, quote, "I really didn't want it to be about my weight because I know that everybody has their weight and has their own issues and I really wanted it to be about the spirit of Weight Watchers and how I was feeling.

--"And I wanted to talk directly to people.  So I didn't want the big body reveal moment.  It's just not really who I am.  And Weight Watchers was on board with that, thankfully."
