Ashlee Simpson, Pete Wentz marry

Los Angeles – Don’t be surprised to find Ashlee Simpson and Pete Wentz grinning like Cheshire cats – they’re newlyweds.

The pop-star little sis of Jessica Simpson and the Fall Out Boy bassist tied the knot Saturday night at her parents’ Los Angeles-area home with an “Alice in Wonderland” theme, according to People magazine.

Simpson, 23, and Wentz, 28, exchanged vows at the property in Encino, a bedroom community in the San Fernando Valley. Joe Simpson, her father, performed the non-denominational ceremony and sister Jessica was the maid of honor, the magazine said.

People also reported Saturday that the couple are expecting a child together, which both Simpson and Wentz have long denied.

Simpson and Wentz began dating in fall 2006 and announced their engagement April 9.
