An anonymous Jon Huntsman advisor says the Huntsman daughters have "gone rogue" in their efforts to promote their dad's candidacy.

Their latest video, the girls parody Justin Timberlake's "Sexy Back" as they insult the rest of the GOP field. The Washington Post reports the latest project took the rest of the campaign by surprise.

"The video was produced without authorization,” said a longtime Republican close to the campaign. “The girls were asked by a number of campaign officials to not release the video. The campaign was not informed of the release of the video. The video does not have a disclaimer and is not a campaign product.”

The spots go against the imposing image Huntsman himself has tried to project. The day before the “SexyBack” video came out, Huntsman himself was talking about the need to “stay focused on the issues that really do matter.”

On the other hand, the serious strategy hasn’t done much for Huntsman so far. The visibility of his daughters is a reminder that Huntsman, who can come off stiff in person, is a human being.

“The videos are great,” said J.P. Freire, a  senior communications strategist with New Media Strategies. “Whoever is doing this knows that content people would enjoy watching is one of the first steps to getting your message out.”
