Ashlee and Pete Tie the Knot

It's official: Ashlee Simpson is now Mrs. Pete Wentz. The rock duo tied the knot last night at her parents' California home in front of 150 guests, including maid of honor Jessica and her date, Tony Romo, along with Nicole Richie and Joel Madden. Ashlee, 23, wore an ivory gown by Monique Lhuillier. Her dad, Joe, performed the non-denominational ceremony -- and Pete's bulldog, Hemingway, was the ring-bearer! After the ceremony, guests partied at an "Alice in Wonderland" themed reception, complete with a cake decorated with a top hat, tea pot and flowers, reports People magazine. Rumors are swirling that Ashlee is expecting her first child with Pete, 28, but the couple haven't confirmed the reports. This is the first marriage for both. [link]
