Aniston, 44, looked lovely in a short, floral-print summer dress, while her fiancé, 41 – who was one of Scott Campbell’s groomsmen – was dapper in a gray suit and black-and-white spotted tie.
Theroux is longtime friends with Campbell, a tattoo artist and fine artist, and both he and Aniston seemed thrilled to be in New Orleans for the nuptials.
Campbell, 36, and Bell, 34, exchanged vows Saturday at the Marigny Opera House. He wore Marc Jacobs, while she looked radiant in a custom-designed Marchesa Couture gown.
