Jessica Simpson is in the final weeks of pregnancy but that didn't stop her from making the trek to Palm Spring last night for an engagement party. Jessica was joined at the bash by her fiancé Eric Johnson, sister Ashlee, Cacee Cobb, Donald Faison, and Adam Brody. Eric stayed by Jess's side throughout the night and chatted with Ashlee's boyfriend, Vincent Piazza. It's the second weekend in a row Jessica has gathered together with loved ones. Friends and family threw Jessica a baby shower last Sunday. Following the pink themed bash Eric was spotted loading up the car with tons of gifts, including more than 20 pairs of tiny shoes.
