Blake Lively and Ryan Reynolds: Um, did anyone even realize these two were engaged?! The Gossip Girl star and Scarlett Johansson's ex-hubby said "I do" in September 2012 in Mount Pleasant, S.C. Although Martha Stewart Weddings helped to plan and cover the top-secret nuptials, not a peep about Mr. and Mrs. Reynolds' classy Southern wedding was leaked before the ceremony.

Evan Rachel Wood and Jamie Bell: These two were trying on wedding bands ages ago, but when they actually made their union official in October 2012, it was certainly a covert operation. Marilyn Mansons ex wed her Adventures of Tintin beau in a small ceremony in California. Other than intel that the bride wore a Carolina Herrera gown, the Wood-Bell nuptials remained a pretty private affair.

Rosie O'Donnell and Michelle Rounds: These lovebirds got married in a private ceremony in New York on June 9. They didn't share their good news, however, until August 2012, a week after Rosie announced she suffered a frightening heart attack and Michelle was diagnosed with desmoid tumors, a life-threatening disease. Rosie posted on her blog that the twosome were the only ones present at their wedding, but wanted to have the "wedding of [our] dreams surrounded by those we cherish" when they were both well enough to do so.
