After a whirlwind engagement and weeks of pregnancy rumours, Ashlee Simpson has married Fallout Boy rocker Pete Wentz in an intimate ceremony at her parents’ home today.

A spokesperson for the couple told People earlier: “We’re delighted to confirm that Pete Wentz and Ashlee Simpson were married this evening in front of family and close friends.”

Only 150 guests were in attendance as 23-year-old Simpson walked down the aisle in an ivory lace gown designed by Monique Lhuillier. To compliment her dress, the singer wore a Neil Lane diamond necklace and earrings set.

Pimp Daddy Joe Simpson, a former pastor, performed the non-denominational ceremony for the young couple, with big sister Jessica as maid of honor and Wentz’ English bulldog, Hemingway, as the ring-bearer.

As reported earlier in the week, the guests were all asked to wear dark, semi-formal clothing. Simpson picked an Alice in Wonderland theme, and with the help of wedding planner Mindy Weiss, created her dream day which included a Sam Godfrey wedding cake on the ‘Mad Hatter Tea Party’, with a top hat, tea pot, stop watch and pot of flowers on top. Large centerpieces of black beauty roses, arranged by Mark’s Garden, completed the fairytale look.

Among the guests were Jessica’s former boyfriend, Dallas Cowboys quarterback Tony Romo, new parents Nicole Richie and Joel Madden, and long-time friend CaCee Cobb and her beau Donald Faison.
