HOUSTON -- Beyoncé -- with family and friends in tow -- endorsed Kamala Harris for president at a campaign rally at Shell Energy Stadium in Houston on Friday night.
"H-Town," Beyoncé declared to thunderous applause when she took the stage in a black blazer dress alongside fellow Destiny's Child member and Houston native Kelly Rowland.
"I'm not here as a celebrity. I'm not here as a politician. I'm here as a mother, a mother who cares deeply about the world my children and all of our children live in, a world where we have the freedom to control our bodies, a world where we're not divided," Beyoncé said.
She encouraged Texans and people watching around the country to vote before introducing the vice president.
Harris entered to Beyoncé's song "Freedom," which has been the theme song of her presidential campaign since it launched this summer.
"To everyone here, we know freedom has never come easy," Harris said. "There has been no moment of our progress as a country that did not come without a fight."
A campaign official said over 30,000 people attended the rally -- Harris' biggest campaign event yet. She was in Texas to discuss reproductive rights and support U.S. Rep. Colin Allred in his attempt to unseat Sen. Ted Cruz.
News broke Thursday that Beyoncé would appear at the rally, and at times Friday the event seemed more like a concert than a political event. At 7 p.m., the lights turned down as the crowd swag surfed. Attendees wore light-up bracelets often seen at concerts like Beyoncé's or Taylor Swift's.
But the only live music would come from country music legend Willie Nelson. Fans have been anticipating a Harris-Beyoncé collaboration ever since rumors of one didn't bear out at the Democratic National Convention in August. They were excited to see the superstar but surely wouldn't have been disappointed if she'd included a musical performance along with her appearance.
Actress Jessica Alba kicked off the event around 7:30 p.m. Ahead of Beyoncé's remarks, her mother, Tina Knowles, and Rowland addressed the audience.
"We cannot accept a country where our daughers and future granddaughters will no longer have the basic freedom that I have lived with for most of my life," Tina Knowles said.
Rowland wore an oversized pinstripe suit with a maroon tie.
"Now Houston, you already had a hand in creating destiny," she said. "So do what you do and do this thing again."
Nelson, who collaborated with Beyoncé on her most recent album, "Cowboy Carter," performed earlier in the evening.
"Are we ready to say Madam President?" Nelson asked before singing "Mammas Don't Let Your Babies Grow Up To Be Cowboys" and "On the Road Again."
The rally focused on reproductive rights and featured doctors and women who have been affected by anti-abortion regulations. Josh Zurawski and Amanda Zurawski of Austin spoke about how Amanda's water broke when she was just 18 weeks pregnant. She had to wait three days, until she was septic, before doctors would terminate her pregnancy.
"I was finally close enough to death to deserve health care in Texas," she said.
Senate candidate Allred took the stage, as well. A recent poll showed his race against Sen. Cruz was at a near-dead heat.
"Everything is bigger in Texas, but Ted Cruz is too small for Texas," Allred told the crowd.
