Jan. 17 (UPI) -- Camila Cabello defended the music of 2019 against Corden's favorite year of 1999 on The Late Late Show.
The pair settled their argument by having a Riff-Off, performing hit songs from both years with help from The Filharmonic.
The late night host eventually admitted defeat and joined Cabello for a rendition of her duet with Mendes, "Senorita."
Cabello set to perform at the 62nd annual Grammy Awards which take place on Jan. 26. The Jonas Brothers, Tyler the Creator, H.E.R., Bonnie Raitt, Rosalia, Run-D.M.C. and Charlie Wilson will aslo be taking the stage.
