JESSICA SIMPSON and hubby-to-be ERIC JOHNSON are dropping their wedding plans – until they both drop some weight!

The blonde beauty has been working hard at slimming down for months, but Eric – a former San Francisco 49er’s football player – is struggling to get his expanding waistline under control.

“Jess and Eric are happier than ever and enjoying a little too much of the good life,” explained an insider. “They were hoping for an early summer wedding, but pushed it back so they both have a chance to shed extra pounds.”

Jessica, 30, who’s been working out with celeb trainer Tracy Anderson, has lost about 20 pounds since last year, when her weight topped out at 150.

But 31-year-old Eric, who is vegan, is having trouble ditching the high-fat foods he loves to snack on.

“He can eat a gigantic bowl of fat-laden guacamole or a one-pound bag of raw al­monds in one sitting, and he justifies it all by saying the food is ‘healthy fat,’” said the insider.

But since neither one wants to look back at their wedding photos with regret, they’ve promised one another they’d both battle the bulge.

Eric proposed to Jessica in November after six months of dating. And although they had originally intended to marry this summer, they started arguing over weight issues.

At one point, when Jess reached 150, Eric told her the wedding was off if she didn’t drop 15 pounds!
