Jessica Simpson weds ex-NFL player Eric Johnson

Singer and fashion entrepreneur Jessica Simpson and her fiance, former NFL pro Eric Johnson, were married on Saturday, following a four-year engagement and two children together.

"We are overwhelmed with complete happiness and love having made our eternal commitment," Simpson, who turns 34 on Thursday, and Johnson, 34, told People magazine in a joint statement.

The 250 guests at the nuptials, held at the San Ysidro Ranch in Santa Barbara, California, included the bride's sister, singer Ashlee Simpson, and her fiance Evan Ross; actress Jessica Alba and her husband, Cash Warren; and former "Scrubs" star Donald Faison and his wife, CaCee Cobb, People said. Among other guests, said E! News, were former "That '70s Show" star Topher Grace and his girlfriend, and Johnson's football compatriots from his alma mater Yale, and the NFL, including former San Francisco 49ers Tim Rattay.

The couple's 1-year-old son Ace, served as ring bearer, People said, and their daughter, Maxwell, 2, was the flower girl, accompanied by her 5-year-old cousin Bronx, Ashlee Simpson's son with her ex-husband, Fall Out Boy rocker Pete Wentz.

The bride wore a custom Carolina Herrera gown, People reported. An instrumental version of Chris Isaak's "Wicked Game" played during the ceremony, said Us Weekly, with E! adding that the newlyweds emerged to The Beach Boys' 1966 ballad "God Only Knows."

Simpson and Johnson began dating in May 2010, though word did not get out until early July. He proposed that November with a three-stone, Neil Lane engagement ring with a central ruby flanked by two diamonds.
