After giving birth in May, Weight Watchers gave Jessica Simpson $3 million to endorse their products and drop her baby weight. Earlier this month she revealed that she'd pretty much accomplished that goal. 

But now she's going to have to do it all over again. Jessica Simpson is expecting another baby.

"It definitely wasn't planned," says a source. "But yes, Jessica is pregnant again."

The baby will be her second with her fiance` Eric Johnson.

"She really is overjoyed," says the source. Even if she's going to have to hit the treadmill all over again. But who cares. Bringing a life into this world is more important than being thin. Right?
