After “The Late Late Show” host James Corden  made the claim that today’s divas are not as fierce as divas of the past, Demi Lovato stopped by to take Corden up on his challenge. The two engaged in the ultimate sing off singing songs from artist like Katy Perry, Adele, and even Aretha Franklin. One thing is for sure we have a whole new R-E-S-P-E-C-T for Corden after watching this.
