...Ariana Grande Performs ‘Problem’ on ‘Dancing With the Stars’ Finale...

In addition to Iggy Azalea, her collaborator Ariana Grande hit the stage on Tuesday’s season finale of “The Voice.” The 20-year-old diva performed her best-selling single of the year, “Problem,” with her troupe of dancers.
While Iggy didn’t join her this time (she had to catch a flight), Ariana held it down all on her own. Even the contestants and judges were seen dancing along.
