But how can she really capitalize on the incessant baby bump watch? Launch a maternity line!
The celeb told Women's Wear Daily that in addition to her wildly successful clothing, shoes and accessories collections, she'll be adding clothing for the stylish mom-to-be into the mix.
See, it's all the rage. Beyonce, who is expecting a child with husband Jay-Z in February, told Harper's Bazaar that she will be creating a line of fashionable maternity wear; and Heidi Klum designed two different maternity lines, Love and Lavish, last year.
Celebs designing maternity gear is a bit frightening (given that the clothes they wear throughout their pregnancies tend to be, uh, untraditional), but if it had to be anyone, we do trust Jessica. While she's had her share of personal fashion flubs, she knows how to create a darn good line of products (and we would know: we own a pair of awesome Jessica Simpson tiger-print flats).
