WATCH: Shawn Mendes Appears In Calvin Klein Videos

Shawn Mendes set the internet on fire over the weekend when he previewed images from Calvin Klein’s spring campaign.

The two photos of the 20-year-old Canadian singer in nothing but boxer-briefs quickly became his most-liked Instagram post ever.

Overnight, Mendes posted a video clip showing him – fully clothed, alas – playing an acoustic guitar and singing part of New Order’s 1987 hit “True Faith.” He captioned it: "So excited about this campaign."

The original version of the song is used in a promotional video for Calvin Klein’s “Our Now” campaign. Mendes appears in the clip – including a shot in which he's eating cereal in his underwear! – along with actor Noah Centineo, rapper ASAP Rocky and model Kendall Jenner.
