Katy Perry to rally Hillary Clinton supporters in Iowa

Katy Perry is publicly showing her support for Hillary Clinton.

The pop singer, in her first appearance for the 2016 campaign, will rally Clinton supporters on Oct. 24 in downtown Des Moines before the presidential nominee attends the Iowa Democratic Party's annual Jefferson-Jackson Dinner, Clinton's campaign announced Saturday morning.

Perry played a hand in rallying supporters for President Barack Obama by playing at numerous events and wearing patriotic dresses she designed herself, including a dress she wore to his rally that had his campaign slogan "Forward" on it and a ballot dress she sported while performing at a Las Vegas rally.

She was a key part of the Obama campaign's strategy to get members of various communities to attend events. Campaign volunteers would sign up attendees to vote and even offer to take them to voting locations if then needed transportation.

The Hollywood Reporter exclusively announced Friday that Christina Aguilera and her producer fiance Matthew Rutler will host Clinton's last big fundraiser of the year on Nov. 4.

The Des Moines event is free and open to the public and registration is encouraged.
