Ashlee Simpson - pregnant with her first child - married her baby daddy, Pete Wentz today, a source confirmed to E! News.

The couple have been engaged for just about a month and have almost 100% confirmed that they are expecting.  They said their vows at Simpson's parents' home in Encino.  A source told People: "We're delighted to confirm that Pete Wentz and Ashlee Simpson were married this evening in front of family and close friends."

Big sis Jessica was Ashlee's maid of honor.  Daddy Joe performed the nondenominational service at about 7 p.m.  Some of the guests included, Jessica's boyfriend (maybe?) Tony Romo, Donald Faison from Scrubs, Cacee Cobb and Pete's Fall Out Boys band mates.  There were a 150 guests in attendance.

Congrats!
