Shawn Mendes and Camila Cabello have performed their new duet on late night US TV.

The duo recently teamed up for Mendes' track 'I Know What You Did Last Summer', which was released on November 18.

This week the pair ran through the track live on The Late Late Show With James Corden.

Mendes worked with the Fifth Harmony singer for his record 'Handwritten Revisited'.

The album is a re-issue of the singer's 2015 debut effort 'Handwritten', with some new tracks included.

Tweeting earlier this month about the track, Cabello said:

"Been writing songs in hotel rooms for years and can't tell u how much it means to me to get to share this with you guys #IKWYDLS."

She added that the track was written backstage at one of Taylor Swift's 1989 Tour shows.
