Ariana Grande got the surprise of a lifetime at Univeral City Walk in Universal City, Calif.
The 20-year-old singer/actress thought she was wrapping up an interview when MyIsh host Todrick Hall starts up a flash mob to songs from her debut album, Yours Truly.
The dancers performed to “The Way,” “Baby I,” “Popular Song,” and more!
Adding to the fun, Ariana‘s brother Frankie Grande also makes a surprise appearance in the mob.
