It's official! Ashlee Simpson and Pete Wentz tied the knot over the weekend at the Simpson family house in Encino, Calif., with dadager/minister Joe Simpson officiating the wedding ceremony. And what else is official? Sources say there's a baby on the way and that Ashlee's four months prego! Who in Hollywood isn't preggers these days?! Sigh.

As for big sis Jessica, Ashlee's maid of honor was accompanied by "boyfriend" Tony Romo even after rumors of a breakup. A source revealed to usmagazine.com that "Joe called Tony and asked him to show support for the wedding." Jess flew to Cabo with her rents after the wedding, so we're pretty sure Tony ditched his Jessica Jinx for good.
