Like many pregnant women, Jessica Simpson has unusual food cravings.
Since she began carrying fiancé Eric Johnson’s baby, the Fashion Star mentor, 31 – who says she no longer likes pizza because it now “tastes sour” – has become obsessed with a particular fruit. But she insists the tasty melon of choice be prepared a certain way.
“I crave cantaloupe like a crazy person,” Simpson told PEOPLE on Tuesday while promoting a skincare line. “But I put salt all over it, so I don’t know if it’s that healthy. I crave anything salty and sweet. That mixture to me is so good. I can eat a whole cantaloupe in one morning.”
