People magazine reports Ashlee Simpson got her fairy-tale wedding to Pete Wentz on Saturday complete with an Alice In Wonderland themed reception.

People says Simpson, 23, and Fall Out Boy bassist Pete Wentz, 28, exchanged vows in front of 150 people at her parent’s home in Encino, a Los Angeles area bedroom community in the San Fernando Valley.

According to the magazine, Joe Simpson, her father, performed the non-denomination ceremony and sister Jessica was the maid of honour.

The bride wore a wedding dress by Monique Lhuillier and a diamond necklace and earrings by Neil Lane, and People says the reception featured a wedding cake with a top hat, tea pot, stop watch and a pot of flowers on top.

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

Simpson, a singer, songwriter and actress, is the younger sister of pop star Jessica Simpson.

A flurry of arrangements on Saturday afternoon just outside the guarded gates of the Simpson’s property indicated that the pop singer’s wedding to Wentz was imminent.

White shuttle vans with tinted windows were streaming through the gates, as were several delivery vehicles, including some marked as belonging to celebrity chef Wolfgang Puck.

Drivers of a few expensive cars who arrived at the guard tower were told to park elsewhere and take a shuttle. One was a well-dressed woman who arrived in an Audi packed with red boxes.

And of course, the paparazzi had been gathering before 3 p.m., lingering outside the property.

Aerial photos posted online Friday on several celebrity websites purportedly showed an outcropping of large white party tents.

Ashlee Simpson’s latest album, Bittersweet World, was released last month. It peaked at No. 4 on the Billboard 200 in its first week, and tracks have logged more than 19 million plays on her MySpace page.
