After much fascination, Beyoncé Knowles showed the world a glimpse of her wedding dress that she wore while marrying Jay-Z in the new live video, “I Was Here."

In the 4.5-minute video, Beyoncé reveals behind the scenes footage of her tour and all the locations she visited around the world. There are cameos by Oprah Winfrey, Jay-Z, Michael Jackson, Tina Turner, and Nelson Mandela.

According to music website Billboard, "I Was Here" splices memories throughout Beyoncé’s life, from home videos of her as a kid, to her early Destiny's Child days, even to her triumphant solo work and love story with musician Jay-Z.

“As expected, there is a quick first glimpse of the star getting fitted into her wedding dress. All this to the soundtrack of Beyoncé's soaring vocal on the soaring ballad, off ‘4’ and written by Diane Warren,” said Billboard.

The singer appears in her wedding dress at 3 minutes into the video; however, fans may have to pause the scene to get a better view of the dress.

Beyoncé’s white flowing wedding dress, with its v-shaped top, was never released to the public previously. In the video, though, the celebrity gives a quick front and back view for the camera.

The 2008 wedding to Jay-Z was kept very private. There were no photographs or videos released from the event, leaving media and gossip columnists to speculate on the nuptials. This is the first behind-the-scenes footage of Beyoncé on her wedding day.

Beyoncé is preparing to give birth to her and Jay-Z’s first child. The superstar couple has been less secretive concerning the pregnancy, by even revealing the news during the 2011 “MTV Music Awards.”

The “I Was Here” video appears in the deluxe "Live at Roseland: Elements of 4” DVD. It hits stores Nov. 29.

A shorter version, "4 Live at Roseland," will be released exclusively through Walmart Nov. 21.
