Demi Lovato and James Corden Have a Diva Riff-Off

Singer, songwriter, and actress Demi Lovato crashes James Corden’s Late Late Show opening monologue to challenge the music-loving late-night host to a sing-off to settle, once and for all, which generation has the fiercest divas.

“When Demi Lovato takes exception to James Corden’s claim that divas such as Cher, Aretha and Tina Turner are more fierce than today’s divas, and the two decide to settle it in a Riff-Off featuring songs from Adele and Katy Perry, with some backing vocals from Level.”
