Details About Mark Zuckerberg's Secret Wedding

Mr. and Mrs. Zuckerberg went to such great lengths to keep their wedding a secret, the bride used an alias when she was dress shopping. INSIDE EDITION has the scoop.

INSIDE EDITION has learned that Facebook billionaire Mark Zuckerberg's new wife made a top-secret mission to a bridal store in Denver, Colorado, to buy her wedding dress.

Desperate to keep the wedding hush-hush, Priscilla Chan used an assumed name, "Priscilla Tuan," when she paid $4,700 for the gown at the Little White Dress store.

The shop is more than 1,000 miles from her home in Palo Alto, California.

Stylist Malea Hutt says Priscilla gave no hint she was about to marry one of America's richest men.

Hutt said, "It was just exquisite on her. It was absolutely the perfect dress for her."

Priscilla had the dress shipped to California for last-minute alterations, the same day her husband-to-be was taking Facebook public.

And get this, the new People magazine revealed that Priscilla walked down the aisle at the backyard ceremony with her Hungarian sheep dog named Beast, by her side.
The gown was by Claire Pettibone, who designed a bridesmaid's dress worn by Cameron Diaz at a wedding in 2006. Even Pettibone had no idea the new Mrs. Zuckerberg would wear her dress.

Meanwhile, Facebook shares continued to do a roller-coaster ride on Wednesday, with the backlash getting more intense.

Federal and local investigators are now looking into reports that big-wig insiders were tipped off that Facebook shares were going to fall once the company went public.

Business Insider editor Henry Blogett said, "Once again, big Wall Street insiders got better information than small investors. And on Facebook, when you have a huge number of small investors wanting to be apart of the IPO, it's especially unfair."
