Still a secret! Blake Lively's rep exclusively tells Us Weekly that the clip accompanying the star's new website, Preserve, does not feature her wedding dress.

"The video that Blake put up is not of Blake and that's not her wedding dress," Lively's rep tells Us. "It is a beautiful dress though!"

Interest in Lively's wedding gown (from her September 2012 nuptials to husband Ryan Reynolds) reached an all-time high last week after the Gossip Girl alum launched her new lifestyle website.

Preserve's interesting introductory video showed images of random people from across America fulfilling their dreams and living out their everyday stories. In one memorable scene, a woman wearing a sparkly white dress (oddly similar in style to the description of Lively's custom-designed Marchesa gown) left viewers speculating whether that was Lively on her wedding day.

While the Age of Adaline star, 26, did not reveal her wedding gown on her new site, she did share the feeling of vulnerability behind working on her latest passion project.

"Sitting down to write this editor’s letter has been the hardest thing I've done yet on my Preserve journey," Lively wrote. "I’m more intimidated than I should probably admit. I'm no editor, no artisan, no expert. And certainly no arbiter of what you should buy, wear, or eat."
