How adorable did super pregnant Jessica Simpson look last night? INF Daily’s photogs caught up with the soon-to-be-mom and fiancee Eric Johnson on their way back from grabbing dinner at Mexicali in L.A. They popped in after celebrating sister Ashlee Simpson’s son Bronx’s third birthday party at The Coop. That’s a afternoon when you’re carrying around a big bump.

Word has it Jessica’s working out a $4 million post-baby Weight Watchers deal. Like current spokesperson Jennifer Hudson, Jess would have a year to slim down using Weight Watchers’ system, and pocket a bucket load of cash for her hard work.

Never expect Simpson to do anything without an endorsement deal behind it. Remember, this is the woman who held out for $500,000 to confirm to a magazine that she was pregnant – and since no one was biting, she ended up having to tell the world for free, via her website. If the Weight Watchers deal doesn’t end up going through, do you think she’ll stay fat until someone pays her enough to lose the pounds?
