Beyonce, Jay Z Headline Star-Studded Hillary Clinton Concert

The stars came out for Clinton in Cleveland.

They're with her.

Jay Z and Beyonce headlined a star-studded concert in support of Democratic nominee Hillary Clinton in Cleveland Friday night.

"We have to think about the future of our daughters, our sons," Beyonce told the crowd at Cleveland State University's Wolstein Center.

She addressed the historical significance of a Clinton presidency, but emphasized that it won't happen unless voters actually head to the polls.

"There was a time when a woman’s opinion did not matter," the singer, 35, said. "If you were black, white, Mexican, Asian, Muslim, educated, poor or rich. If you were a woman. It did not matter. Less than 100 years ago women did not have the right to vote. Look how far we’ve come from having no voice to being on the brink of making history. Again. By electing the first woman president. Yes! But we have to vote."

Beyonce said she was thrilled when her nephew witnessed the election of Barack Obama to the White House, but now, she sayd, it's time for daughter Blue Ivy, 4, to witness a woman in the White House.

"Eight years ago, I was so inspired to know that my nephew, a young black child, could grow up knowing his dreams could be realized by witnessing a black president in office," she said. "And now, we have the opportunity to create more change. I want my daughter to grow up seeing a woman lead our country. And know that her possibilities are limitless. We have to think about the future of our daughters, our sons, and vote for someone who cares for them as we do. And that is why I’m with her."

Jay Z echoed his wife's comments, adding, "We are on the doorsteps of history. We’re here tonight, I’m here tonight because respect matters, respect matters to me."

And without naming Clinton's GOP rival Donald Trump, Jay Z said, "This other guy I have no ill will towards him. He is divisive so he cannot be my president, he cannot be my president. Once you divide us you weaken us."

The husband-and-wife duo met with Clinton ahead of the concert.

Beyonce took to the stage after Jay Z performed. He brought along several other rappers, including J. Cole, Big Sean and Chance the Rapper.
