Ariana Grande performs ‘Problem’ on ‘Dancing With the Stars’ finale...

Last night on Tuesday’s season finale of 'The Voice,' Ariana Grande performed her best-selling single of the year, 'Problem.' For the performance, the 20-year-old was joined on stage by a troupe of dancers (sans Iggy Azalea), while belting out the uptempo number.

Ariana has been putting in some serious effort with the stage presence and it's good she is leaving her quinceanera looks in the past. However, how is it possible to have the catchiest of songs and no one can sing along to it? She sings like she took her denchers out, and for Monroe Carey to have better enunciation than her is in deed a real 'problem.' Check out the performance below.
