Jessica Simpson and Eric Johnson grabbed lunch at Hals in Venice, CA, yesterday. They got into the St. Patrick's Day spirit in green gear, with Jessica carrying an emerald Hermès bag and sporting Hunter boots in the same hue. Eric went all out in green pants, a bright shirt, a hat, and a plaid umbrella for the occasion. A palm tree branch fell on the sidewalk right in front of Jessica as they walked on Abbot Kinney, though Eric held onto her arm to avoid a spill. Jessica and Eric were joined by family and friends for the festivities, which came after a Friday date night for the duo at Mr. Chow in LA. Jessica and Eric are prepping for the arrival of their first child, with rumors swirling that they plan to name the baby girl Maxwell, which is Eric's middle name.
