Orlando Bloom helped Katy Perry with DNC speech

Orlando Bloom helped his girlfriend Katy Perry perfect her speech for the Democratic National Convention (DNC) in Philadelphia, Pennsylvania.

The 31-year-old singer addressed the crowd about the importance of voting before her performance of new single Rise at the political convention on Thursday (28Jul16).

Katy, who has endorsed the Democratic Party's presidential nominee Hillary Clinton, said: "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.

"So I'm asking you to have an open mind and to use your voice, because on November 8th, you'll be just as powerful as any NRA (National Rifle Association) lobbyist. You'll have as much say as any billionaire. Or you can just cancel out your weird cousin's vote, if you like."

"It's not where you come from; it's what you grow into," she added.

While the Roar hitmaker didn't mention her Orlando's name on stage, he was in the audience, proudly filming his girlfriend's appearance on his cell phone.

HelloGiggles co-founder Sophia Rivka Rossi live-tweeted Perry's speech on Thursday and was clearly impressed with one powerful phrase.

"It's not where you come from, but what you grow into," she posted, tagging the pop star and using the hashtag "#DNCinPHL."

The singer subsequently responded to Sophia, revealing the Pirates of the Caribbean star was in fact responsible for contributing the poignant line to her piece.

"Lando (sic) put that one in", she proudly revealed, adding a red heart emoji to show her love for her man.

Convention-goers spotted the pair holding hands backstage, and an eye-witness told People.com, "Katy's eyes conveyed her emotions. Orlando was happy. You could tell."

Katy endorsed Clinton for president last October (15) and has since campaigned for the candidate at numerous fundraisers. And it's not the first Democratic candidate she's supported, despite her parents being Republican. In 2012, she performed at multiple events in support of President Barack Obama's bid for re-election to the White House.

Clinton will go up against her Republican Party rival Donald Trump when the nation heads to the polls in November.
