Christina Aguilera better watch her back. Not only is Ariana Grande throwing out more vocal runs than Mariah Carey on a treadmill, but the pop tart is coming for Xtina's Queen of Diva Impressions crown.
In her first-ever late night talk show interview, Ari faced off with serial impressionist Jimmy Fallon on a duet to the classic theme from Beauty and the Beast.
Fallon, "singing" the Peabo Bryon part, does what Fallon does best -- provide a seque for other people to outshine him. Not only does Ari have the pipes, but she's also got the accent and chest-thumping down to a science.
