The 67th United States Secretary of State Hillary Clinton, brought out two big names at a Saturday rally in Iowa - the American politician who served as the 42nd President of the United States from 1993 to 2001 - Bill Clinton and American singer, songwriter, and actress - Katy Perry. The former U.S. President Clinton introduced the 'Dark Horse' singer - Katy Perry.

69 year old Bill Clinton said to the Des Moines crowd, which had gathered before the Iowa Jefferson-Jackson Democratic dinner, "Look, I don't want to talk long, for the reason that I have never been the warm-up act for Katy Perry before. I am well concerned that I am the warm-up act."

The performance of Katy Perry included the hits "Wide Awake" "America the Beautiful," and "Firework" - which was all geared towards supporting the presidential candidate - Hillary Clinton. 31 year old Katy Perry also performed her hit single "Roar."

Katy Perry stated to her fans, "How many of you are going to be 18 next year, before November? Are you going to vote? For the reason that you have the power, right?" "Listen, you have so much power and this is going to be one of the most significant elections in over a decade." "So much change can happen. Let's go Hillary!"

Katy Perry, famous for sporting memorable outfits at political events, put on a white dress with a flowing American flag behind it, similar to a cape. Perry held the symbolic American flag cape out as the singer delivered the last notes of the opening track, "Roar."

However, some of the crowd was gathered for the political engagement, while some individuals lined up hours before the doors opened simply to watch a free show from Katy Perry.

As for 63 year old Dave Barloon of Iowa City, he came to the event to hear a thing from Hillary Clinton and continued saying that he considered seeing Katy Perry as an added bonus for the rally.
