Pete Wentz, Ashlee Simpson's Wedding Had 'Alice In Wonderland' Theme, 'Emotional' Toast From Jessica: Reports

Bride's pregnancy status remains unclear, despite initial report.

Pete Wentz and Ashlee Simpson's wedding Saturday night was a non-denominational, Alice in Wonderland-themed ceremony that was presided over by Ash's dad, Joe Simpson, with sister Jessica, serving as bridesmaid.

The wedding, which took place in the backyard of Joe and Tina Simpson's Encino, California, home, was attended by approximately 150 guests, including Nicole Richie and Joel Madden, "Scrubs" actor Donald Faison and girlfriend Cacee Cobb, as well as Jessica's maybe/ maybe not boyfriend, Dallas Cowboys quarterback Tony Romo, according to Us Magazine. The bride, 23, wore an ivory lace Monique Lhuillier dress and a diamond necklace with matching earrings, while Wentz, 28, wore a Dior Homme tuxedo.

While's initial, "exclusive" report on the wedding seemed to confirm rumors that Simpson is pregnant — saying that she is "pregnant with the couple's first child," although there were no quotes from Wentz or Simpson on the matter — at press time, the wording had been altered to read, "who sources say is pregnant with the couple's first child," and a representative for the couple told MTV News on Monday (May 19), "We have not, nor did we ever, confirm anything but the wedding." Wentz denied that Simpson is pregnant when asked about the rumors last month by MTV News, but speculation has continued.

People aso reported that Wentz's English bulldog, Hemingway, served as the ringbearer, and that the reception featured a Wonderland-inspired cake with a top hat, teapot, stopwatch and a pot of flowers on top, with elaborate centerpieces with black beauty roses. Guests sipped on Veuve Clicquot champagne and danced to music from a DJ after dinner. OK! added that the bridesmaids wore black Vera Wang gowns and celebrity chef Wolfgang Puck catered the event.

One unnamed guest told E! Online that the wedding was a "magical" and beautiful" event that bore the imprint of the Simpson clan's hands-on patriarch, dubbing it the "Joe Simpson Show."

After escorting his youngest daughter down the aisle, the site reported that Joe Simpson told the guests funny and touching stories about Ashlee before beginning the wedding, frequently choking up during the ceremony. "They were all crying," the source said, "it was very moving."

Big sister Jessica was reportedly a bit glum during the wedding, but did give an "emotional, off-the-cuff" toast at one point, according to E!, saying that Pete and Ashlee's relationship, "had inspired [her] to love again." Wentz's brother also gave a toast.

Strangely, for a wedding of two musicians, E! reported that there was no live band, and no one danced until after the cake was cut.

The guests gathered underneath white tents, which were decorated with black rugs, white couches with red pillows, black chandeliers and lots of red roses, the site reported. At the couple's request, all the guests wore dark colors. After taking pictures, E! reported that Ashlee emerged in a "sexy black party dress" to dance, and claimed that it was barely noticeable that she was pregnant with the couple's first child. Though guests were required to check their cell phones and cameras at the door, they did leave with a memento: a red box containing a cookie that, continuing the "Alice in Wonderland" theme, read, "Eat me."
