'One of our national treasures.' Beyoncé pays tribute to Willie Nelson ...

Texas music royalty reunited for a Kamala Harris rally in Houston on Friday, Oct. 25. Beyoncé Knowles-Carter, 43, introduced the 2024 Democrat Presidential Nominee to the thousands of people gathered to support the current Vice President. Willie Nelson performed two of his classic songs earlier that night.

91-year-old country legend Willie Nelson, who was just in Austin to celebrate the 50th anniversary of "Austin City Limits," played “Mama Don’t Let Your Babies Grow up to Be Cowboys” (1979) and “On the Road Again” (1980) at the rally.

Beyoncé pays tribute to 'The Great Willie' on Instagram

Three days after the rally, Beyoncé posted a heartfelt tribute to Nelson, who she referred to as “The Great Willie” on Instagram.

“You were so kind to me and the girls of Destiny’s Child when we fanned out meeting you years ago,” Knowles-Carter said. “And you greeted me with the same kindness 20 years later!”

“You are the coolest! I admire you, and I sincerely thank you for being the pioneer you are. Thanks for your impactful music, your advocacy, and the gracious way you appreciate and celebrate other artists! You are 1 of 1,” Knowles-Carter said.

“You are one of our national treasures,” Knowles-Carter said. “Sending my love to you.”

Beyoncé spoke 'as a mother' at Harris rally

While Beyoncé did not perform as she did for Hillary Clinton’s Cleveland rally in 2016, the song “Freedom” off her 2016 album “Lemonade” has been the anthem of the Harris campaign since July.

“I’m not here as a celebrity. I’m not here as a politician. I’m here as a mother, “ Knowles-Carter said as she introduced Harris. “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.”

The superstar singer addressed the audience alongside former Destiny’s Child member Kelly Rowland. “Imagine our daughters growing up seeing what’s possible with no ceilings, no limitations,” Knowles-Carter said. “We must vote, and we need you.”
