Hillary Clinton is wrapping up the last weekend of her presidential campaign with a "Roar" with the help of pop star Katy Perry.
On Saturday, the Democratic nominee's campaign unveiled its new television ad set to Perry's hit song, airing it in 11 battleground states in her fight against Republican rival Donald Trump, reports The Washington Post.
The ad buys are in Arizona, a traditionally red state where polls say the Democratic nominee may have a chance, and in the states of Colorado, Florida, Iowa, Michigan, Nevada, New Hampshire, North Carolina, Ohio, Pennsylvania and Wisconsin.
Clinton has been in the lead in Michigan and Wisconsin, but Trump has been making a push in the Democratic-leaning states.
The new ad shows images of dozens of voters, with captions that declare they're voting for courage, respect, fairness and other qualities, as Perry's hit song plays in the background.
The pop singer, who was one of Clinton's earliest endorsers, will perform a benefit concert in Philadelphia, along with music legend Stevie Wonder, for the former secretary of State Saturday night, and Clinton is scheduled to appear on stage.
Perry is just one of several stars performing to benefit the Democratic nominee, and also performed at the Democratic National Convention in July.
Friday night, rapper Jay Z and his superstar wife, Beyonce, performed for Clinton's campaign in Cleveland Friday night, and last week, Jennifer Lopez joined Clinton in Miami.
Rival candidate Donald Trump has ridiculed the celebrity endorsements, saying Saturday that he regularly draws crowds of tens of thousands of supporters without having to result to people like Jay Z to bring in huge audiences.
