Jessica Simpson is reportedly pregnant with her first child with fiancé Eric Johnson, according to In Touch Weekly.

She's already having kooky cravings! a source told the magazine, adding that Simpson has been eating everything from nacho chips dipped in chocolate to cheese-flavored popcorn.

If the rumors are true, Simpson, 31, and Johnson, 32, will be preparing for the arrival of a spring baby.

Last November, the couple announced their engagement, six months after dating and one month after Johnson's divorce was finalized. Simpson was previously married to 98 Degrees singer Nick Lachey from 2002-2006.

Signs of Simpson's pregnancy were first spotted just weeks ago, when the couple celebrated Johnson's 32nd birthday. Before making a birthday toast to Johnson, the singer sent back a glass of champagne in exchange for a non-alcoholic option, a source told In Touch.

Since the announcement of her engagement, Simpson has remained mum about the wedding specifics.

With a wedding, it should be a celebration like we should all be having fun, every single person there . . . I've heard people throw around dates, and not one of them has nailed it. Not even close, she told celebrity Web site Just Jared in August.
