Jessica Simpson Celebrates Her Baby Shower

Jessica Simpson is expecting a baby girl – and her family and friends have already started helping her celebrate!

On Sunday afternoon, her nearest and dearest gathered in Los Angeles for a baby shower organized by celebrity event planner Mindy Weiss.

Simpson wore her hair down with soft braids around her face and sported a light blue dress that showed off her pregnant belly. She was joined by Jessica Alba and sister Ashlee. And when Ashlee arrived with son Bronx, Jessica greeted them outside the party.

"Jessica looked pretty and very happy," says an eyewitness.

Adds a friend: "She's so excited to be a mom. She can't wait to meet her little girl."
