If you blink you will miss a two-second glimpse of Beyonce’s wedding gown in a new video for her single “I Was Here.”

Near the end of the four-and-a-half-minute video, which appears on vevo.com, Beyonce shares a quick peek at the front and back of her white strapless flowing dress. The singer, who kept her 2008 wedding to Jay-Z a closely guarded secret, has never before revealed the dress publicly.

The gown has an exaggerated sweetheart neckline and fitted back with what appears to be layers of fabric and a long train.

The video is like a home movie featuring highlights from Beyonce’s decorated life, starting from her days performing as a young girl and later as a member of Destiny’s Child, to performing solo at sold-out concerts and holding an armful of Grammy Awards, to most recently revealing her baby bump at the 2011 MTV Video Music Awards.

As Beyonce sings, “I wanna say I lived each day until I die,” the video shows her with such famous faces as Nelson Mandela, Michael Jackson, Oprah Winfrey, Tina Turner and the Obamas.

But it’s the personal moments the singer’s fans will no doubt devour, like seeing her play in the water, stroll hand-in-hand with husband Jay-Z and pose in her wedding gown.
