Exactly as expected, Ashlee Simpson and Pete Wentz tied the knot at her parents' home in Encino, CA on Saturday afternoon. According to People, the ceremony was officiated by Joe. Jessica acted as maid of honor and her date for the night was Tony Romo. Pete's bulldoggie Hemingway acted as ring bearer, though it sounds like there's definitely a baby on the way. Nicole Richie and Joel Madden were among the 150 guests as were Donald Faison and CaCee Cobb. Ashlee's rep said, "We're delighted to confirm that Pete Wentz and Ashlee Simpson were married this evening in front of family and close friends." The reception was Alice in Wonderland themed. Congrats to the happy couple — we can't wait to hear more details from their big day!
