Katy Perry performs 'Rise' and 'Roar' in support of Hillary Clinton at Democratic National Convention

Perry gave a heartfelt speech about the importance of voting before her performance

Katy Perry has performed in support of Hillary Clinton at the final night of the Democratic National Convention in Philadelphia.

The pop star gave a heartfelt speech about the importance of voting before singing her new single, Rio Olympics anthem “Rise” , and empowering 2013 hit “Roar” just before the US presidential candidate took to the stage.

Perry, dressed in a sparkling silver dress, was accompanied by her actor boyfriend Orlando Bloom, who recorded her performance on his phone.

“Both of my parents are pastors and staunch Republicans. I didn’t finish high school and unfortunately I don’t have a formal education, but I do have an open mind and I have a voice,” the 31-year-old said.

“I’m asking you to have an open mind and to use your voice because on [election day] 8 November you’ll be just as powerful as an NRA lobbyist. You’ll have as much say as any billionaire. Or you can just cancel out your weird cousin’s vote, if you like. Because remember, it’s not where you come from, it’s what you grow into. Let’s roar for Hillary!”

Perry has been joining Clinton on her campaign trail since endorsing her for president in October. In 2012, she also performed at multiple events to support President Obama’s campaign.

Numerous high profile musicians have performed at the DNC over the past week, from Carole King’s beautiful rendition of “You’ve Got a Friend” to Paul Simon singing his classic “Bridge Over Troubled Water”.

Multi-talented actor Elizabeth Banks produced and directed a Pitch Perfect-inspired a cappella version of Rachel Platten’s motivational “Fight Song” featuring a host of stars from Sia and Bruce Cohen to Idina Menzel and Alan Cumming.

“Living in history, America take a bow, we’re about to show the world, that women are equal now,” raps Ester Dean halfway through in a nod to the historic nomination that could see Clinton become the first female US president.
