While Mark Zuckerberg was taking Facebook public, his longtime girlfriend Priscilla Chan was quietly putting the final touches on her wedding gown.

In a surprise relationship status update, Zuckerberg and Chan married Saturday in a small, unannounced ceremony at their home in Palo Alto, Calif.

The bride looked stunning in Claire Pettibone’s “Sky Between the Branches” gown, an ivory laser-cut floral dress with matte sequins lined in silk.

The gown featured subtle cutouts in the overlay, plus an illusion jewel neckline, sheer back and chapel-length train. Chan's dress retails for $4,700.

Pettibone, a Los Angeles-based designer, has also created wedding dresses for stars like Mad Men's Elisabeth Moss and American Idol's Tamyra Gray.

Guests thought they were merely coming over for a surprise party to celebrate Chan’s graduation from medical school at the University of California.

However, the couple, who met at Harvard more than nine years ago, had been planning the low-key wedding for more than four months.

Given that Facebook stock is already down $4 today, at least Mark has something to smile about ... well that and being worth tens of billions.

Congratulations to the newlyweds again!

Four behind-the-scenes photos have surfaced showing The Amazing Spider-Man star Andrew Garfield and his stunt double, William Spencer, in action (click the thumbnails to enlarge).

The Amazing Spider-Man stars Garfield along with Rhys Ifans, who also starred in this year's The Five-Year Engagement (check out our The Five-Year Engagement quotes page), and Emma Stone. Stone got her start five years ago in the hit high school comedy Superbad (here are some Superbad quotes), and five years later she's still playing a high schooler.

The highly anticipated superhero film opens July 3. In the meantime, if you stare long enough at The Amazing Spider-Man logo, it kind of looks like it's twitching. That's almost as good as seeing the film, right?
