Tears of joy! Ariana Grande surprises fans during sing-off on TODAY

You can’t win ’em all. But sometimes, all can win.

Four Ariana Grande fans who visited the TODAY plaza Thursday to compete for VIP passes to the singer’s Friday performance on the show each ended up with a ticket — and a surprise sing-along with their favorite pop star.

Mother-and-daughter duo Heather and Paige faced off against pals Jailyn and Dana. Each team sang a few bars of Grande’s megahit “Problem,” with Matt, Tamron, Al and Dylan listening carefully in an attempt to choose the winning team.

“I don’t think we’re qualified,” Tamron lamented.

So who better to judge than Grande herself? Gripping a wireless mic and singing along with the fans, the pop star emerged from the studio unannounced to render a verdict.

“Not gonna lie — that was pretty good!” Grande complimented the stunned teams, as an overwhelmed Paige blotted happy tears from her cheeks with a sweatshirt sleeve.

Grande then handed VIP badges to all four contestants. Talk about ending summer with a "Bang"!

Tune in Friday when Grande performs live on the TODAY plaza. "My Everything," her second studio album, is out now.
