Ariana Grande and Bernie Sanders Finally Unite at Singer's Concert After Twitter Exchange

There was a special guest in attendance at Ariana Grande's concert in Atlanta on Tuesday night—Vermont Senator Bernie Sanders.

The 26-year-old shared a string of photos she took alongside the Democratic nominee following her performance on Instagram on Wednesday. "MY GUY. thank you Senator Sanders for coming to my show, making my whole night and for all that you stand for!!!" Grande wrote.

Grande, who has vocally supported members of the Democratic Party before, noted she's used her Sweetener tour to encourage fans to exercise their right to vote. Through her partnership with HeadCount, a nonprofit organization that works with musicians to promote voter registration, Grande said more than 20,000 concertgoers have signed up for voter registration.

"@headcountorg and I are doing our best to make you proud. we've already registered 20k+ young voters at my shows and more online and we aren't stopping any time soon. proud of my fans for paying attention and getting involved. we adore you! also... i will never smile this hard again," she wrote.

Maroon 5, J. Cole, Vampire Weekend, Billie Eilish and several other musicians have partnered with HeadCount on their nationwide tours to also assist concertgoers with registering to vote if they are interested.

Sanders, who is currently campaigning for a spot on the ballot for the 2020 election, commented on the "Thank U, Next" singer's post shortly after. "Thank you Ariana Grande for not only being a wonderful entertainer, but also for being such an outstanding advocate for social justice. We must all be prepared—like Ariana—to fight for everyone who is struggling," he wrote.

The pair's official meet comes just a few weeks after their Twitter exchange went viral. Referencing Lizzo's chart-topping song "Good As Hell"—of which Grande appears on the official remix—the singer asked her legion of social media fans, "baby, how you feelin'?" in October.

Thousands of fans responded to the tweet, including 78-year-old Sanders, who used the moment to promote his progressive political agenda, Medicare for All. "Ready to fight for Medicare for All," he wrote.

Shocked by his participation in her tweet, Grande later responded to his message by writing, "Screaming."

Sanders' Medicare for All proposal is one of the leading policies of the senator's campaign. The proposal aims to give more people access to healthcare coverage at a lower cost by incorporating a government system to manage and regulate healthcare. Eliminating co-pays, premiums and deductibles are at the core of the proposal along with providing better options for inpatient and outpatient hospital care coverage, emergency services, preventative service and access to prescription drugs. The plan also includes dental and vision coverage.
