Scarlett Johansson, Alicia Keys and Gisele Bundchen: Hollywood’s Top-Secret Weddings (PHOTOS)

In a surprise ceremony that stunned Hollywood, Avatar star Giovanni Ribisi and supermodel Agness Deyn tied the knot on June 16 in Los Angeles, Calif.

The 37-year-old actor and his 29-year-old model-bride weren’t even publicly dating – their hush-hush marriage may not even had become public if it hadn’t been for a local reporter who visited the registrar’s office to pick up her child’s birth certificate.

It’s certainly not the first time that a celebrity couple has snuck off for a top-secret wedding.

From Scarlett Johansson and Ryan Reynolds to Alicia Keys and Swizz Beatz, Hollywood’s A-listers have often pulled off the seemingly impossible: a quiet ceremony void of any flashing cameras and hubbub.

Now, Celebuzz has compiled a list of all those couples — check out our gallery above to see the happy brides and grooms!
