Ashlee Simpson and Pete Wentz are grinning like Cheshire cats right now because the two got married on Saturday.

Ash and Wentz tied the knot in an Alice in Wonderland theme wedding at Simpson's parents home in Encino, Calif. Ashlee's older sister, Jessica, was the maid of honor and Dallas Cowboys QB Tony Romo was her date.

People.com is saying that Ashlee and Pete confirmed that they are expecting their first child.

Any guesses on baby names? How about Mad Hatter?
