Bernie Sanders went to Ariana Grande's concert and she 'will never smile this hard again'

Ariana Grande is majorly feeling the bern.

The singer posted photos of herself and Sen. Bernie Sanders on Twitter, thanking the presidential candidate for coming to her concert in Atlanta last night.

"MY GUY," she wrote. "Thank you Senator Sanders for coming to my show, making my whole night and for all that you stand for!"

"Also I will never smile this hard again promise," she added.

Sanders also posted about meeting the "Thank U, Next" singer to thank her 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 has shown — to fight for everyone who is struggling," he wrote.

The pop star has partnered with HeadCount to register voters at her concerts. According to Grande, the organization has already registered over 20,000 young voters at her shows alone.

This isn't the first time Grande has gushed about Sanders on social media. Last month, she and the Vermont senator had a back-and-forth on Twitter.

After Grande tweeted the Lizzo lyrics, "baby how u feelin," Sanders responded saying, "Ready to fight for Medicare for All." Grande later retweeted Sanders' response, adding "screaming."
