Pregnant Jessica Simpson -- Baby Bulging at the Seams!

Jessica Simpson is a huge star and it shows.

Wearing a slimming black sheer frock, the glowing mom-to-be successfully maneuvered her growing baby bump through the streets of Ojai, California this weekend.

Although she looks like she's about to pop, the 32-year-old singer/actress/fashion mogul -- who already has an adorable one-year-old daughter -- isn't due until around July.

While Jess has revealed she's having a boy this time, it is going to be a belly long month or so until he finally arrives.
