Update: Givenchy has denied speculation that it will collaborate with H&M. According to Vogue UK, the house says rumors about the partnership are "false." And while H&M never commented on the Givenchy rumor, its creative adviser Margareta van den Bosch told The Telegraph it will "not have any [collaborations] for Spring. We decided to skip it, as we have had so many this year. So it'll be something for next November."

The Internet has been aflutter with rumors that H&M's next designer collaboration will be with Givenchy, and so far, both parties are keeping mum on the topic.

On Monday, a Givenchy representative told Fashionologie that the house does "not have a comment"; a spokeswoman at H&M said the retailer "does not comment on rumors."

But radio silence from both brands hasn't stopped fervent speculation, which was sparked by a Nov. 19 post on the Tumblr Fashion Industry Confessions. The author of the post claimed, "Rumors straight from the Givenchy headquarters have it that they will collaborate with H&M next year." The claim has since been bolstered and questioned by blogs and Twitter accounts far and wide, but confirmed by no one.

The last time H&M kept quiet about a rumor, it was when rumors ran rampent about the company's plans to start a higher-priced label. We all know how that turned out: & Other Stories is set to launch in Spring 2013.

If this latest rumor pans out, then it would make Givenchy and Riccardo Tisci the first LVMH house and designer to partner with H&M. But whether there's a deal between the two brands or not, the time for H&M to announce its next designer collaboration is drawing nearer. The retailer unveiled plans for its Spring 2012 partnership with Marni on Nov. 29, 2011.
