Demi Lovato, James Corden Have Diva Riff-Off on Late Late Show — Watch

James Corden challenged Demi Lovato to a divalicious duel on Wednesday, facing off against the “Cool For the Summer” singer in a fierce battle of sass, voice and song.

The showdown was prompted by the Late Late Show host, who claimed they “just don’t make divas like they used to,” citing the likes of Tina Turner, Aretha Franklin, Whitney Houston and Cher. Lovato, of course, took umbrage with this sentiment, triggering an intense virtuosic riff-off between the multi-platinum recording artist and the CBS funnyman.

Corden and Lovato were accompanied by Level, who provided a capella background vocals on songs by Adele, Katy Perry and Gloria Gaynor. The full setlist went as follows:

* “Rolling In the Deep” by Adele (Lovato)

* “River Deep, Mountain High” by Tina Turner (Corden)

* “Respect” by Aretha Franklin (Corden)

* “Roar” by Katy Perry (Lovato)

* “Heart Attack” by Lovato (Lovato)

* “I Will Survive” by Gloria Gaynor (Lovato and Corden)
