Ariana Grande rocked the Today show on Friday morning, performing hits "Problem," "Break Free," "Break Your Heart Right Back" and an abbreviated version of her new collaboration with Nicki Minaj and Jessie J, "Bang Bang" (although the other two singers weren't there).

Ariana fans flooded Rockefeller Center plaza for the free show, many of whom began lining up over 24 hours before her performance.

Host Matt Lauer chatted with the singer before her performance, asking her how she's been dealing with the instant fame that came with her music career.

"Well, I spend a lot of time with my family... I'm very grateful for my fans... It's a blessing," she said. "I just have to constantly remind myself how lucky I am to do what I love."
