The newly cemented husband and wife swapped vows on the ranch's luscious lawn in a traditional ceremony. The scene was set against a backdrop of lavish rose gardens under a canopy with chevron seating, a source told E! News exclusively.
More than 250 guests attending the couple's nuptials, including Jessica's sister Ashlee Simpson and her fiancé Evan Ross, Jessica Alba and her family, Topher Grace and his girlfriend, and Johnson's old football buddies from Yale and the NFL, including Tim Rattay.
Live music played as guests arrived at the ranch at about 4 p.m. and they witnessed Jessica and Eric make it official about an hour later, a source said. Many of the women in attendance were spotted in brightly-colored gowns in shades of pink, champagne, gold and turquoise, while male guests sported black tuxedos and suits with either black ties or bow ties.
According to People, Jessica rocked a custom Carolina Herrera gown for her walk down the aisle to her hubby-to-be, with the couple later telling the mag, "We are overwhelmed with complete happiness and love having made our eternal commitment. To say 'I do' in front of family, friends and, most importantly, our children has been the happiest moment of our lives."
The couple's daughter, 2-year-old Maxwell, served as the flower girl, walking down the aisle with Ashlee's 5-year-old son Bronx. Meanwhile, Jessica and Eric's 1-year-old son, Ace, served as the ring bearer.
As the wedding came to a close, guests could be heard cheering, applauding and screaming for the bride and groom. Live music played again once the ceremony was over.
