Ariana Grande and Mac Miller Perform on 'Today' Concert Series

Ariana Grande kicked off her release week on a high note. Fans packed Rockefeller Plaza as the 20-year-old diva-in-training took over the “Today” Toyota Concert Series for a performance on Tuesday. She put her powerful pipes on display while singing “Tattooed Heart” off her debut Yours Truly.

She also brought out Mac Miller to perform their hit “The Way.” During his opening verse, the rapper shouted out Lil B. “Thank you, Based God,” he said.

Yours Truly is already No. 1 on iTunes in over 30 countries including the U.S.

“I was hoping that it would do well, but I didn’t expect it to go to No. 1 so quickly!” said Grande.
