"We're delighted to confirm that Pete Wentz and Ashlee Simpson were married this evening in front of family and close friends," a family rep told People.
Jessica Simpson, who served as Ashlee's maid of honor; her apparently still-willing beau, Tony Romo; Nicole Richie and Joel Madden; Scrubs star Donald Faison and his girlfriend, longtime Jessica pal and family friend Cacee Cobb; and Wentz's fellow Fall Out Boys were among the 150 guests in attendance.
Joe Simpson performed the nondenominational service.
