ICYMI, Taylor Swift dropped her clapback 'Look What You Made Me Do' video during the VMAs, and wow, just wow.

The vid was filled with major disses directed at a number of celebs, including her ex Calvin Harris.

Written on one  of the gravestones featured in the clip was the name 'Nils Sjöberg' - this was the pen name Taylor used when she co-wrote Calvin's hit 'This Is What You Came For.'

And after their split, Tay Tay took credit for the track and Calvin went on a little rant about it on Twitter, so clearly it's a v. sensitive topic.

Calvin attended yesterday's event and cameras captured his reaction the exact moment it premiered.

According to this clip obtained by The Mail Online, he refused to clap afterwards unlike the rest of the crowd...

Calvin & Taylor parted ways last year in June, after 15 months of dating.
