candidacy in October and headlined a major rally in Iowa

It pays to be best friends with a wealthy Democratic presidential candidate.

Pop star Katy Perry endorsed Hillary Clinton for the White House back in October and has been tirelessly promoting her candidacy both at high-profile campaign events and on social media, where she has tens of millions of followers.

Now it has emerged that Perry's production company, Kitty Purry Inc, was paid $70,000 in December from the coffers of the Hillary for America campaign.

Nailed it: In October, Perry posted this photo of her Clinton-inspired manicure on the candidate's own Instagram page

Public records obtained by the Washington Free Beacon suggest that the Clinton campaign hired Perry's company to produce an event for the presidential hopeful, but the documents do not reveal what services Kitty Purry Inc rendered.

In late October, Perry headlined a Clinton rally in Iowa, appearing on stage alongside the presidential candidate and her husband, Bill Clinton, in a white strapless dress emblazoned with Hillary's campaign logo.

'You're gonna hear us roar - to 2016 and beyond!' Perry shouted from the stage during an afternoon concert that drew a crowd of 4,000 people.

Of Clinton, she said 'she's my firework' and urged members of the audience to support her.

For Clinton’s birthday, which fell on a Monday following the big rally in Iowa, Perry presented the former secretary of state with a gold pendant that spelled out the acronym 'POTUS,' which stands for ‘President of The United States.’

Perry's company was also paid more than $128,000 by Barack Obama’s 2012 re-election campaign. At an Obama rally in Las Vegas that year, Perry donned a latex dress decorated with a ballot paper

The Firework songstress and Elton John are scheduled to perform a concert for Clinton donors in March.

Perry's company was also paid more than $128,000 by Barack Obama’s re-election campaign for services involving an unspecified political event.

The campaign reported cutting a check for Kitty Purry Inc on November 26, 2012, more than two weeks after Obama was re-elected for a second term.

According to the documents, the six-figure payment went towards a host of services, including venue rental, sound, light, staging, travel and accommodations.

During the 2012 campaign, Perry emerged as a staunch supporter of the incumbent president, even donning a latex dress decorated with a ballot paper during a Las Vegas rally.

At another campaign event in Wisconsin, Perry showed up wearing a blue frock adorned with Obama’s slogan 'Forward.'

Last week, 23-year-old pop singer Run Weaver publicly accused Perry on Twitter of endorsing Hillary Clinton in exchange for money.

Perry, 31, sent out a tweet on February 12 promoting her upcoming benefit concert for Hillary's donors. In response, Weaver wrote: 'LOLOLOL SORRY NOT SORRY OLEASE (sic) OPEN UR EYES.. THIS TWEET IS IGNORANT IF NOT FUNDED BYE.'
