Ariana Grande Says Bernie Sanders is Her Guy After He Attends Her Show

If Bernie Sanders wins the Democratic nomination for President … he might have this endorsement from one of the biggest pop stars in the world to thank.

Ariana Grande just shared a couple photos with the 78-year-old Vermont Senator, thanking him for hitting up her concert in Atlanta Tuesday night and “making my whole night and for all that you stand for !”

She went on to say she’s doing her best to register young voters and has already gotten more than 20k sign-ups at her shows. She added … “i will never smile this hard again promise.”

From the looks of it … Bernie might not either!!!

Sanders is in town for tonight’s fifth primary debate, which will feature 10 contenders for the Democratic nomination. Not that he needs the energy boost … but ya gotta think a plug from Grande will provide one anyway.

BTW — this isn’t the first time Ariana and Bernie have had a noteworthy connection … last month she posted “baby how u feelin” on Twitter, and he replied by tweeting he’s ready to fight for Medicare for All.
