Earlier in the weekend, Jess and Eric attended the rehearsal dinner for the wedding of pals Bret Harrison and Lauren Zelman. Jess is a bridesmaid in their wedding party!

“She was a good sport about being a bridesmaid even though she is so pregnant,” a witness told Us Weekly. “It definitely wasn’t easy for her to get around and help the bride.”

FYI: Jessica is wearing a Camilla maxi dress.
