Oh, baby! Jessica Simpson showed off her ever-expanding baby bump when she stepped out for a family dinner with her 1-year-old daughter Maxwell, her sister Ashlee, and Ashlee's 4-year-old son Bronx in Ojai, California, on Sunday.

The "Fashion Star" mentor, who is (super) pregnant with her second child with fiancé Eric Johnson, rocked a skintight black maxi-dress at the gathering — tight enough, in fact, to be borderline see-through over her midsection. While it's unclear whether the peek at her belly button was intended, the 32-year-old looked unconcerned as she strolled along with her hand resting on her bump.

Simpson completed her maternity look with a black jacket, oversize shades, huge hoop earrings, comfy flat sandals, and a show-stopping orange bag. But even that bright purse couldn't divert one's eyes from her impressive bump. This second-time mommy-to-be looks just about ready to deliver!

And she's certainly prepared for her new addition. Simpson has spent the last several months getting ready to welcome her son and make Maxwell a big sister.

As part of her baby prep, the mogul recently put her $8 million pad up for sale and has reportedly already picked out a name for her forthcoming bundle of joy. In addition, back in April, she was feted at a glamorous baby shower, where guests sipped drinks from vintage baby bottles and received condoms as party gifts (since this pregnancy was admittedly a "surprise").

Though it's likely to be a few more weeks until she welcomes her family's latest addition, she looks good to go, so let the countdown begin!
