Hatching a cleverly conceived plot to continue her relationship with Jenny Craig, or Weight Watchers, or whatever, Jessica Simpson is reportedly pregnant again.

Seven months after giving birth to daughter Maxwell Drew Johnson, the singer is once again knocked up, according to Us Weekly.

"It definitely wasn't planned. But yes, Jessica is pregnant again," a source reveals to Us. The surprise baby-to-be is the second for Simpson and her fiance, former San Francisco 49ers tight end Eric Johnson.

Him again? He sure hit the fertility jackpot.

A rep for Simpson had no comment. Which is basically the same as hanging a sign outside the office, screaming "CONGRATULATIONS ON YOUR NEXT JENNY CRAIG CONTRACT, JESSICA SIMPSON!"

Simpson, as you may have figured out, made a lot of money from Jenny Craig, losing 70 pounds of post-baby weight. Now guess what she gets to do? That's right -- time to pull a stool up to the buffet.

Engaged for the past two years, Simpson, 32, and Johnson, 33, welcomed Maxwell -- a whopping 9-pound, 13-ounce bundle of joy -- on May 1.

"Motherhood is a dream," Simpson told Katie Couric in September. "It really is absolutely amazing."

I'll bet it's a dream ... when you have enough money to pay someone to get up in the middle of the night to deal with the diaper-bombs.
