Most brides can't wait to tell everyone they know about their engagements and developing wedding plans.
But others decide to keep the details quiet, waiting to shock friends with their wedding news by hosting surprise ceremonies.
Click through the slideshow below to see couples who surprised their guests -- and the general public -- with their "guerrilla" weddings.
Retirement Party Turned Wedding
Two police officers from Schaumburg, Ill. shocked friends and family when their retirement party turned into a wedding ceremony. <a href="http://www.dailyherald.com/article/20120624/news/706249783/" target="_hplink">The <em>Daily Herald</em> reports</a> that officers Libby Watkins and Mike Conjura disappeared from their own June 2012 party, then their 150 guests were moved into their backyard to witness the couple's vows.

Passengers aboard the Yellow Line in Washington D.C were <a href="http://www.huffingtonpost.com/2012/06/11/wedding_n_1587122.html#slide=more231856" target="_hplink">witnesses to the marriage</a> of Kaarin Moore and Navin Vembar in June 2012. "They chose to get married on the yellow line, once we crossed into D.C., to show their solidarity for the District's same-sex marriage equality law," the couple's wedding photographer, Stacy Vaeth, told the Huffington Post in an email.
