The expecting star was positively glowing in her white Grecian Alice + Olivia maxi, which she paired with loose curls, simple silver jewellery, coral nails and seriously tall cork platforms.
While the sex of her newcomer is yet to be confirmed, rumour has it that Jessica received a fair few pink presents during her baby shower at the weekend - pointing to a possible new sister for three-year-old daughter Honor Marie.
