Speculation went rampant, and gossips the Internet over believed the frock might be the dress Lively wore during her surprise nuptials to actor Ryan Reynolds in September 2012.
Alas, it was not.
"The video that Blake put up is not of Blake and that's not her wedding dress," her rep told Us Weekly.
So everyone just calm down.
Speaking of the dress, though, Lively did share some tidbits about the Marchesa gown in her recent interview for the August issue of Vogue -- specifically how her husband made her love the gown again despite some serious damage following a drastic sparkler incident at the wedding.
Sparkler like the fireworks kind, not the put-on-the-ring-finger kind.
"I get really frustrated when something goes wrong. For example, my wedding dress. Florence Welch was singing at the reception, and they brought out these sparklers, and I'm watching her sing. I look down and my wedding dress has a big burn mark from one of the sparklers. Right on the front! And it was just so heartbreaking to me," the 26-year-old told the mag.
"And later, my dress was hanging up and Ryan said, 'Isn't that beautiful?' I said, 'What?' And he pointed to the burn. My heart just stopped, because it was such a sensitive little subject. And he said, 'You'll always remember that moment with Florence singing and the sparklers. You have that forever, right there, preserved.' Now that's my favorite part of the dress."
Though no full photos of the couple in their wedding regalia have been available to the public, Lively and Reynolds gave readers a glimpse at their South Carolina nuptials in a feature for Martha Stewart Weddings a few months after the event.
