Adele and her fans are at war against US presidential candidates who are using the singer’s fame and music for their campaign.

The British singer’s camp told presidential candidates that they do not have permission to use her songs at campaign rallies following the outrage of fans during the Republican presidential candidate where Donald Trump used Adele’s hit songs in his sorties.

The Independent cited a statement issued by the singer’s spokesman: “Adele has not given permission for her music to be used for any political campaigning.”

Trump and his running mate, vice presidential candidate Sarah Palin, earlier used Adele tracks from her “21” album – “Rolling in the Deep” and “Skyfall”- as walk-out music during their rallies. These actions made Adele’s fans furious, Washington Post wrote.

USA Today noted that Adele’s publicist’s statement was not specifically aimed to the real estate mogul. Trump is just the most current violator of appropriating the music of singers and bands for their campaign events.

Earlier last month, Chris Christie tweeted a video response to attack the ads by Marco Rubio that are set to the tune of “Hello.” He also told an audience at a campaign event that he recently “kind of fallen in love with Adele.”

Just last week, former Arkansas governor Mike Huckabee’s campaign released an ad parodying the British power-ballad queen’s song “Hello.”

Trump was also asked earlier by Aerosmith lead singer Steven Tyler to stop using “Dream On” at his campaign events. The Republican candidate also used Neil Young’s “Rockin’ in the Free World” and the singer himself reprimanded the presidential hopeful.

Political candidates allegedly still ignore the law that an artist’s work can’t be used to sell or promote anything without permission, USA Today noted.

Meanwhile, there have been reports of some plans about a feature film of Adele’s upcoming world tour.

“There is huge interest in a feature film of Adele’s tour. It would undoubtedly be a huge box office hit around the world,” a source told the Daily Star Sunday.

Adele reportedly allowed a film crew to follow and document her behind the scenes. However, the plans for the films is still uncertain and the singer could scrap the idea if she becomes “too stressed.”
