Singer/reality TV star Jessica Simpson tied the knot with fiancee Eric Johnson Saturday at San Ysidro Ranch in Montecito, CA, five miles east of Santa Barbara.

People reports that 250 guests attended the wedding, including her parents Joe and Tina Simpson, sister Ashlee Simpson with fiance Evan Ross, and former personal assistant Cacee Cobb and husband Donald Faison.

The couple's 1-year-old son, Ace, served as ringbearer, and their daughter, 2-year-old Maxwell, was flower girl, alongside Ashlee's 5-year-old son Bronx.

"We are overwhelmed with complete happiness and love having made our eternal commitment," the couple told People in an exclusive statement Saturday afternoon. "To say 'I do' in front of family, friends and, most importantly, our children has been the happiest moment of our lives."
